Answer:
18x^2 + 27x - 35
Step-by-step explanation:
f(g(x)) means function f times function g. substitute for f and g, which gets you (3x+7)(6x-5). Now, multiply using the distributive property.
3x * 6x = 18x^2
3x * -5 = -15x
7*6x = 42x
7 * -5 = -35
The equation then becomes 18x^2 - 15x + 42x - 35. Simplify the equation.
18x^2 stays, -15x and 42x combine to make 27x, and the -35 stays too.
Finally, you get the equation, 18x^2 + 27x -35.
