Question

Factorize the expression x(x -2)(x - 4) + 4x - 8

Answer 1

Step-by-step explanation:

(x²-2x)(x-4)+4x-8

x³-4x²-2x²+8x+4x-8

x³-6x²+12x-8

Answer 2

Step-by-step explanation:

x(x -2)(x - 4) + 4x - 8

identity - (x+a)(x+b) = x^2 + (a+b)x + (ab)

x( x^2 -6x + 8) + 4x -8

x^3 - 6x^2 + 8x + 4x -8

x^3 - 6x^2 + 12x - 8

☆ After this ,

if you want to factorise further -

• Use Hit and Trial Method
• Long division
• Theorem - Divident = Divisor × Quotient + Remainder
• Splitting the middle term

Hope it helps
