Question

Determine the factors of x2 − 9x + 20.

Answer 1

x^2-9x +20=0

x^2 -5x -4x +20=0

x(x-5) -4(x-5)=0

(x-4) (x-5)=0

So Factors are
(x-4)(x-5)

Answer 2

x^2-9x=-20

x^2-9x+20=0

x^2-5x-4x+20=0

x(x-5)-4(x-5)=0

(x-4)(x-5)=0

=> Factors are
(x-4)(x-5)

Answer 3

how come we get the same answer

Answer 4

hmmmmm that amazing

Answer 5

because we derived the answer for the same question :P

Answer 6

@zahabaha so x=4 and x=5
