Chapter 9.2, Problem 9E

To determine

To write the equation in standard form

Answer to Problem 9E

The standard form is $4x^2-12=0$

Explanation of Solution

Given information:

  $4x^2=12$

Calculation:

The standard equation is $a{x}^2+bx+c=0$

The given equation is $4x^2=12$

To make the equation in standard form, subtract -12 from both sides,

  $4x^2-12=12-12$

Solving,

  $4x^2-12=0$

Hence, the standard equation is $4x^2-12=0$
