Question

factorize the following x^2-8x+16

Answer 1

This is the required answer

Answer 2

Answer with explanation

split the middle term in which both the numbers 16 and -8 have the same factors when multiplied and added.

so you get,

x^2 - 4x - 4x + 16

take the common factors,

x(x-4)-4(x-4)

take the common brackets and the left out stuff.

your final answer will be,

(x-4)(x-4)
