factor 7x^2-13-2

factor

7 x^{2} - 13 - 2

(7 x + 15) (7 x - 15)

Solution steps

7 x^{2} - 13 - 2

Subtract the numbers:

- 13 - 2 = - 15

= 7 x^{2} - 15

Rewrite

7 x^{2} - 15

(7 x)^{2} - (15)^{2}

= (7 x)^{2} - (15)^{2}

Apply Difference of Two Squares Formula:

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

(7 x)^{2} - (15)^{2} = (7 x + 15) (7 x - 15)

= (7 x + 15) (7 x - 15)

x^{8} - 21 x^{4} - 46

3 sin^{2} (x) - 5 sin (x) + 2

2 + 22

\frac{30}{50}
