Question

If f(x) = 5x2 – 3x + 4 and g(x) = 2x – 5, what is f(x) • g(x) ?

Answer 1

Is simple as multiply both functions.

f(x)*g(x)=(5x²-3x+4)(2x-5)

Answer 2

Simplifiyng would be

f(x)*g(x)=(10x³-25x²-6x²+15x+8x-20)

Simplifying this

f(x)*g(x)=(10x³-31x²+23x-5)

Answer 3

you did something wrong it should either end with +20 or -20

Answer 4

Yeah is -20 at the end i got mistaken.

Answer 5

Thats ok
