Write in the form (x+p)^2+q
x^2−10x

(x - 5)² - 25

Step-by-step explanation:

Using the method of completing the square

add/ subtract ( half the coefficient of the x- term)² to x² - 10x

x² + 2(- 5)x + 25 - 25

= (x - 5)² - 25

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
