Answer:

x = - 4, x = 11

Explanation:

Given

x² - 7x - 34 = 10 ( subtract 10 from both sides )

x² - 7x - 44 = 0 ← in standard form

Consider the factors of the constant term ( - 44) which sum to give the coefficient of the x- term ( - 7)

The factors are - 11 and + 4, since

- 11 × 4 = - 44 and - 11 + 4 = - 7, hence

(x - 11)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 11 = 0 ⇒ x = 11

x + 4 = 0 ⇒ x = - 4
