The correct factor is (2x - 3) and (2x + 3).
<h2>Quadratic equation</h2>
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
Given
4x² -9 = 0 is a quadratic equation.
<h3>To find </h3>
The factor of the given equation.
<h3>How to find the factor of the given equation?</h3>
4x² -9 = 0 is a quadratic equation.
According to factorization,
4x² - 9 = 0
(2x)² - 3² = 0
( 2x - 3 ) ( 2x + 3 ) = 0
Thus the correct factor is (2x - 3) and (2x + 3).
