Question

4x²-8x + 4 Factorise

Answer 1

Answer:

Factorisation of 4x²-8x+4

Factorisation of 4x²-8x+4= 4(x-1)(x-1)

Step-by-step explanation:

Given quadratic polynomial:

4x²-8x+4

= 4(x²-2x+1)

= 4[ x² - 2×x×1 + 1²]

= 4(x-1)²

/* By algebraic identity :

a²-2ab+b² = (a-b)² */

= 4(x-1)(x-1)

Therefore,

Factorisation of 4x²-8x+4

= 4(x-1)(x-1)
