Regroup the terms and factorise: z – 19 + 19xy – xyz. Covid-19 has led the world to go through a phenomenal transition . Here x is common factor in x3 + x and – 3 is common factor in – 3x2 – 3, Therefore x3 + x – 3x2 – 3 = (x – 3) (x2 + 1), Question 2: Factorize a(a + b)3 – 3a2b(a + b), Question 3: Factorize x(x3 – y3) + 3xy(x – y), Question 4: Factorize a2x2 + (ax2 + 1)x + a, Question 6: Factorize x3 – 2x2y + 3xy2 – 6y3, Question 7: Factorize 6ab – b2 + 12ac – 2bc, Taking 6a common from first two terms and –b from last two terms, Question 8: Factorize (x2 + 1/x2) – 4(x + 1/x) + 6, = (x2) + (1/x) 2 + ( -2 )2 + 2x(1/x) + 2(1/x)(-2) + 2(-2)x, As we know, x2 + y2 + z2 + 2xy + 2yz + 2zx = (x+y+z) 2, Therefore, x2 + 1/x2) – 4(x + 1/x) + 6 = (x + 1/x – 2) 2, Question 9: Factorize x(x – 2) (x – 4) + 4x – 8, Question 10: Factorize ( x + 2 ) ( x2 + 25 ) – 10x2 – 20x, Expanding the middle term of ( x2 – 10x + 25 ), Therefore, ( x + 2) ( x2 + 25) – 10x ( x + 2 ) = ( x + 2 )( x – 5 )2, Question 11: Factorize 2a2 + 2√6 ab + 3b2, Above expression can be written as ( √2a )2 + 2 × √2a × √3b + ( √3b)2, Therefore, 2a2 + 2√6 ab + 3b2 = (√2a + √3b )2, Question 12: Factorize (a – b + c)2 + (b – c + a) 2 + 2(a – b + c) (b – c + a), (a – b + c)2 + ( b – c + a) 2 + 2(a – b + c) (b – c + a), Question 13: Factorize a2 + b2 + 2( ab+bc+ca ), Therefore, a2 + b2 + 2ab + 2bc + 2ca = ( a + b )( a + b + 2c ), Question 14: Factorize 4(x-y) 2 – 12(x – y)(x + y) + 9(x + y)2, Expanding the middle term, -12 = -6 -6 also 4× 9=-6 × -6.

Factorize each of the following expressions: Therefore, p3 + 27 = (p + 3)(p² – 3p – 9), Therefore, y3 + 125 = (y + 5)(y2 − 5y + 25), Therefore, 10x4 y – 10xy4 = 10xy (x−y)(x2 + xy + y2), = (a −2b−8b) {(a−2b)2 + (a−2b)8b + (8b) 2}, =(a −10b)(a2 + 4b2 − 4ab + 8ab − 16b2 + 64b2), = (a+b−(2a−2b))((a+b)2+(a+b)(2a−2b)+(2a−2b) 2), =(a+b−2a+2b)(a2+b2+2ab+(a+b)(2a−2b)+(2a−2b) 2), =(a+b−2a+2b)(a2+b2+2ab+2a2−2ab+2ab−2b2+(2a−2b) 2), Question 1: Factorize 64a3 + 125b3 + 240a2b + 300ab2, = (4a)3 + (5b) 3 + 3(4a)2(5b) + 3(4a)(5b)2 , which is similar to a3 + b3 + 3a2b + 3ab2, We know that, a3 + b3 + 3a2b + 3ab2 = (a+b)3], Question 2: Factorize 125x3 – 27y3 – 225x2y + 135xy2, Above expression can be written as (5x)3−(3y) 3−3(5x)2(3y) + 3(5x)(3y)2, Question 3: Factorize 8/27 x3 + 1 + 4/3 x2 + 2x, Question 4: Factorize 8x3 + 27y3 + 36x2y + 54xy2, Above expression can be written as (2x)3 + (3y) 3 + 3×(2x)2×3y + 3×(2x)(3y)2, Which is similar to a³ + b³ + 3a²b + 3ab² = (a + b) ³], Therefore, 8x3 + 27y3 + 36x2y + 54xy2 = (2x+3y)3, Question 5: Factorize a3 − 3a2b + 3ab2 − b3 + 8, Again , Using: a3 + b3 =(a + b)(a2 – ab + b2)], a3 − 3a2b + 3ab2 − b3 + 8 =(a−b+2)(a2+b2−2ab−2a+2b+4), = (a+2b+4c)(a2+(2b)2 + (4c)2−a×2b−2b×4c−4c×a), Therefore, a3 + 8b3 + 64c3 − 24abc = (a+2b+4c)(a2 +4b2 +16c2 −2ab−8bc−4ac), = (x + (−2y) + 3z) (x2 + (−2y)2 + (3z) 2 −x(−2y)−(−2y)(3z)−3z(x)), =(x −2y + 3z)(x2 + 4y2 + 9 z2 + 2xy + 6yz − 3zx), = (3x – y – z){ (3x)2 + (- y)2 + (– z)2 + 3xy – yz + 3xz)}, = (3x – y – z){ 9x2 + y2 + z2 + 3xy – yz + 3xz)}, = (x/3 + (−y) + 5z)((x/3)2 + (−y)2 + (5z) 2 –x/3(−y) − (−y)5z−5z(x/3)), = (x/3 −y + 5z) (x^2/9 + y2 + 25z2 + xy/3 + 5yz – 5zx/3), = (2x) 3 + (3y) 3 +(−6y) 3 −3(2x)(3y)(−6z), = (2x+3y+(−6z)){ (2x)2+(3y) 2+(−6z) 2 −2x×3y−3y(−6z)−(−6z)2x}, = (2x+3y−6z) {4x2 +9y2 +36z2 −6xy + 18yz + 12zx}, = (5+2x+(−3y)) (52 +(2x) 2 +(−3y) 2 −5(2x)−2x(−3y)−(−3y)5), Question 7: (3x−2y)3 + (2y−4z) 3 + (4z−3x) 3, Let (3x−2y) = a, (2y−4z) = b , (4z−3x) = c, We know, a3 + b3 + c3 −3abc = (a + b + c)(a2+b2+c2−ab−bc−ca), ⇒ (3x−2y)3 + (2y−4z) 3 + (4z−3x) 3 = 3(3x−2y)(2y−4z)(4z−3x), Question 8: (2x−3y)3 + (4z−2x) 3 + (3y−4z) 3, Let 2x – 3y = a , 4z – 2x = b , 3y – 4z = c, a + b + c= 2x – 3y + 4z – 2x + 3y – 4z = 0, (2x−3y)3 + (4z−2x) 3 + (3y−4z) 3 = 3(2x−3y)(4z−2x)(3y−4z).
