3x^2 =15 standard form

3x^2 - 15 = 0

-x^2 + 14 = 0

-2x^2 + 4x - 5 = 0

Step-by-step explanation:

3x^2 = 15

3x^2 - 15 = 0

-x^2 = -14

-x^2 + 14 = 0

4x - 2x^2 = 5

-2x^2 + 4x - 5 = 0

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
