(3x-1) (x²-3x+4)

Multiply the brackets together

3x(x^2-3x+4)

3x^3-9x^2+12x

-1(x^2-3x+4)

-x^2+3x-4

3x^3-9x^2+12x -x^2+3x-4

3x^3-9x^2-x^2+12x+3x-4 (just rearranging)

3x^3-10x^2+15x-4

Answer: 3x^3-10x^2+15x-4

Which is f(5) for the function -2x2 + 2x - 3?

Schach [20]

The value of f(5) is -37

Solution:

Given function is:

$f(x) = -2x^2+2x+3$

We have to find the value of f(5)

To find the value of f(5), we have to substitute x is equal to 5 in given function

Plug in x = 5 in f(x)

$f(x) = -2x^2+2x+3\\\\f(5) = -2(5)^2+2(5) + 3\\\\\text{Simplify the above expression }\\\\f(5) = -2(25) + 10 + 3\\\\\text{Solve the above expression }\\\\f(5) = -50 + 10 + 3\\\\f(5) = -40 + 3 = -37$

Thus value of f(5) is -37
