Answer:
<h2>x = -1 or x = 7</h2>
Step-by-step explanation:
Answer:
x = - 1, x = 7
Step-by-step explanation:
Given
x² - 6x - 7 = 0
Consider the factors of the constant term (- 7 ) which sum to give the coefficient of the x- term
The factors are - 7 and + 1, since
- 7 × 1 = - 7 and - 7 + 1 = - 6, hence
(x - 7)(x + 1) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 1 = 0 ⇒ x = - 1
