factor 2x^2-7-9

factor

2 x^{2} - 7 - 9

2 (x + 22) (x - 22)

Solution steps

2 x^{2} - 7 - 9

Subtract the numbers:

- 7 - 9 = - 16

= 2 x^{2} - 16

Factor out common term

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

= 2 (x^{2} - 8)

Factor

x^{2} - 8 : (x + 8) (x - 8)

= 2 (x + 8) (x - 8)

Refine

= 2 (x + 22) (x - 22)

(x^{2} - x) - 4

[t sin (Bt)]

x - 5 h 4 - 15 h 3 - 10 h 2

(x + 3)^{2} - 7 (x + 3) + 12
