Question

Find the quotient of quantity of negative 5 times x to the 3rd power plus 15 times x to the 2nd power minus 10 times x all over negative 5 times x. (5 points)

x2 + 3x − 2
x2 − 3x + 2
−x2 + 15x − 10
x2 − 15x + 10

Answer 1

The answer for this question would be: the second one.

Answer 2

x^2 - 3x +2

Explanation:

`(-5x^3+15x^2-10x)/(-5x)`

We divide the whole expression by -5x

When we divide by negative the sign of each term changes

We divide each term separately by -5x

-5x^3 / -5x = x^2

15x^2 / -5x = -3x

-10x/ -5x = +2

So the expression becomes x^2 - 3x +2
