factor 4x^2-12+9

factor

4 x^{2} - 12 + 9

(2 x + 3) (2 x - 3)

Solution steps

4 x^{2} - 12 + 9

Add/Subtract the numbers:

- 12 + 9 = - 3

= 4 x^{2} - 3

Rewrite

4 x^{2} - 3

(2 x)^{2} - (3)^{2}

= (2 x)^{2} - (3)^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(2 x)^{2} - (3)^{2} = (2 x + 3) (2 x - 3)

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