Question

Factor. x2−9x+20 Enter your answer in the box.

Answer 1

actors of x2−9x+20 are (x - 4) and (x - 5)

Explanation:

It is given that,

p(x) =x2−9x+20

Factorize using splitting method

p(x) =x2−9x+20

20 = 5*4 and 5+4 = 9

p(x) = x2−4x - 5x + 20

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

= (x - 4)(x - 5)

Therefore factors of x2−9x+20 are (x - 4) and (x - 5)

Answer 2

(x-4) (x-5)

Explanation:

x^2 -9x+20

What two number multiply to 20 and add to -9

-4*-5 = 20

-4+-5 = -9

(x-4) (x-5)
