factor

7 x^{2} - 10 x - 8

(7 x + 4) (x - 2)

Solution steps

7 x^{2} - 10 x - 8

Break the expression into groups

= (7 x^{2} + 4 x) + (- 14 x - 8)

Factor out

x

from

7 x^{2} + 4 x : x (7 x + 4)

Factor out

- 2

from

- 14 x - 8 : - 2 (7 x + 4)

= x (7 x + 4) - 2 (7 x + 4)

7 x + 4

= (7 x + 4) (x - 2)

45 z^{2} - 20 z^{4}

- x^{2} + 9 x = x^{2} - 5 x

m z - 5 m h^{2} - 5 n z + 25 n h^{2}

10 x^{2} + 10 x - 698 = 0

(x - 1) (x + 6) (x - 4) \geq 0
