Question

If the right-hand side of a quadratic equation does not equal zero, you need to ______ the number or expression on the right-hand side from both sides before you can use the quadratic formula.

Answer 1

If the right hand side of a quadratic equation does not equal zero, you need to subtract the number...

Answer 2

We have two cases here:

Case 1:

If
we have a quadratic equation of the form:

`ax^(2) +bx = c`

Now if we need to bring c to the left side , we will have to subtract it from left side.

`ax^(2) +bx- c=0`

Case 2:

we have a quadratic equation of the form:

`ax^(2) +bx = -c`

Now if we need to bring c to the left side , we will have to add it on the left side.

`ax^(2) +bx+c=0`

Answer : If the right-hand side of a quadratic equation does not equal zero, you need to either add or subtract the number or expression on the right-hand side from both sides before you can use the quadratic formula.
