factor

5 x^{2} - 2 x - 7

(x + 1) (5 x - 7)

Solution steps

5 x^{2} - 2 x - 7

Break the expression into groups

= (5 x^{2} + 5 x) + (- 7 x - 7)

Factor out

5 x

from

5 x^{2} + 5 x : 5 x (x + 1)

Factor out

- 7

from

- 7 x - 7 : - 7 (x + 1)

= 5 x (x + 1) - 7 (x + 1)

x + 1

= (x + 1) (5 x - 7)

\frac{( 2 x ^{(2)} - 7 x ^{(2)} - 20 x + 25 )}{( 2 )} = 0

70 = - 16 t^{2} + 70 t + 5

\frac{a - b}{( b - a ) ^{2}}

v^{2} + 2 v + 1 = 0

10 u^{2} + 17 u + 3 = 0
