Answer:
2x² - 9x - 35
Step-by-step explanation:
f(x) × g(x) = (x - 7)(2x + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
x(2x + 5) - 7(2x + 5) ← distribute both parenthesis
= 2x² + 5x - 14x - 35 ← collect like terms
= 2x² - 9x - 35
Answer:
18
Step-by-step explanation:
3 x 3 = 9
9 x 2 = 18
Answer:
1. f = -9
2. x = -7
3. x = -9
4. x = -20
5. y = 7.5
