Step-by-step explanation:
[tex] {x}^{2} - 2x + 7x - 14[/tex]
[tex] {x}^{2} + 5x - 14[/tex]
Answer:
x² + 5x - 14
Step-by-step explanation:
Given
(x + 7)(x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 2) + 7(x - 2) ← distribute both parenthesis
= x² - 2x + 7x - 14 ← collect like terms
= x² + 5x - 14
