Question

If f ( x ) = 3x^2 + x - 3 and g ( x ) = 5x, find f ( x ) g ( x )

Answer 1

Answer:
`\Large\boxed{15x^2+5x^2-10x}`

Explanation:

Given information

f(x) = 3x² + x - 3

g(x) = 5x

Given expression

f(x) g(x)

Substitute values into the given expression

(3x² + x - 2) (5x)

Expand the parenthesis by distributive property

3x² · 5x + x · 5x - 2 · 5x

(3 · 5) (x² · x) + 5 (x · x) - (2 · 5) x

`\Large\boxed{15x^2+5x^2-10x}`

Hope this helps!! :)
