Question

x2 - 22x +117
steps to step​

Answer 1

Answer:

x^2-22x+117=-0

x^2-22x=-117

x^2+x=117/22

Answer 2

x²-22x+117

So in this type of factorisation method, the middle term should be divided into 2 parts such that the sum gives the middle term and the product gives the last term.

x²-22x+117

x²-9x-13x+117 {(-9)(-13) = 117} {-9-13=(-22)}

x(x-9)-13(x-9)

(x-13)(x-9)

Hope it helps

Have a great day
