Write the quadratic equation whose roots are −2 and 2, and whose leading coefficient is 3.
Elena L [17]

Answer:

3x^2-12=0

Step-by-step explanation:

<u>Quadratic Equation</u>

A quadratic equation also called a second-degree equation is a special polynomial whose highest degree is two.

The general form of the quadratic equation is

ax^2+bx+c=0

Where a is known as the leading coefficient. Another form to write the quadratic equation is

a(x-x_1)(x-x_2)=0

Where x1 and x2 are the roots or zeroes of the equation.

We have the roots of the given equation are -2 and 2, and the leading coefficient is 3.

Plugging in the given values we have

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

Operating

3(x^2-4)=0

\boxed{3x^2-12=0}

PLEASE HELP; WILL GIVE BRAINLIEST - GEOMETRY
Ede4ka [16]
If you are trying to simplify 36(pi)/4, then 9(pi) would be what you want because it is the simplest form of that fraction. It also depends on the answer choices. Sometimes they want simplest form and other times they’ll have you leave the fraction as is. Typically simplifying completely is your best bet though.

Hope this helps!
