Question

What is 6x^3 - 3x^2 + 7x - 4
when x = 5?

Answer 1

Answer:
706

Explanation:
Substitute x=5 in the equation:
6(5)^3 - 3(5)^2 + 7(5) - 4
= 6(125) - 3(25) + 35 - 4
=750 - 75 + 35 - 4
=706
So the answer is 706

Answer 2

Explanation:

`= {6x}^(3) - {3x}^(2) + 7x - 4`

`= 6 * 125 - 3 * 25 + 7 * 5 - 4`

`= 750 - 75 + 35 - 4`

`= 750 + 35 - 75 - 4`

`= 706..`
