factor 7x^2+(-4)

factor

7 x^{2} + (- 4)

(7 x + 2) (7 x - 2)

Solution steps

7 x^{2} + (- 4)

Rewrite

7 x^{2} + (- 4)

(7 x)^{2} + 2^{2}

= (7 x)^{2} + 2^{2}

Apply Difference of Two Squares Formula:

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

(7 x)^{2} + 2^{2} = (7 x + 2) (7 x - 2)

= (7 x + 2) (7 x - 2)

sec^{2} (+ (x + c))

(x + h)^{2} + 2 (x + h) + 1

2.565 x + (- 12.44025)

x 3 + x + x 2 + 1 + a 2 + a 2 x

a x^{2} - b x^{2} + 3 a - 3 b
