Question

X^2-7x+10=(x-5)(x- )what’s the missing number

Answer 1

-2.

Explanation:

The +10 is the product of - 5 and the missing number:

+10 = -5 * -2.

Answer 2

(x - 2)

Explanation:

Given the quadratic

x² - 7x + 10

To factor consider the factors of the constant term ( + 10) which sum to give the coefficient of the x- term ( - 7)

The factors are - 5 and - 2 since

- 5 × - 2 = + 10 and - 5 + (- 2) = - 7, thus

x² - 7x + 10 = (x - 5)(x - 2)
