factor 9x^2-12+4

factor

9 x^{2} - 12 + 4

(3 x + 22) (3 x - 22)

Solution steps

9 x^{2} - 12 + 4

Add/Subtract the numbers:

- 12 + 4 = - 8

= 9 x^{2} - 8

Rewrite

9 x^{2} - 8

(3 x)^{2} - (8)^{2}

= (3 x)^{2} - (8)^{2}

Apply Difference of Two Squares Formula:

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

(3 x)^{2} - (8)^{2} = (3 x + 8) (3 x - 8)

= (3 x + 8) (3 x - 8)

Refine

= (3 x + 22) (3 x - 22)

(a x^{2}) + 2

0.04 - 0.4 x + x^{2}

x^{8} - 5 x^{4} - 14

C (8.2)

9 - 0.8 (0)^{2}
