g(x) = 3x2 + 5x – 5
Find: g(f(x))
Answer:
Step-by-step explanation:
g(x - 6)= 3(x - 6)^2 + 5(x - 6) - 5
= 3(x^2 - 12x + 36) + 5x - 30 - 5
= 3x^2 - 36x + 108 + 5x - 35
= 3x^2 - 31x + 73
3x^2-5x=2
Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x² - 100 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 100
= x² - 10²
= (x - 10)(x + 10)
