Simplify the following expression.

C.

Step-by-step explanation:

First, we can set up our expression as such

When you divide two numbers with the same base and different powers, all you do is subtract the lower power from the upper.

In this case the powers are and

This means that the power would be

Now we can put this power back on its base and then simplify.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

the square root of what number? if you add that, then someone will probably answer the question.
