factor 21x^2+23x-20

factor

21 x^{2} + 23 x - 20

(7 x - 4) (3 x + 5)

Solution steps

21 x^{2} + 23 x - 20

Break the expression into groups

= (21 x^{2} - 12 x) + (35 x - 20)

Factor out

3 x

from

21 x^{2} - 12 x : 3 x (7 x - 4)

Factor out

5

from

35 x - 20 : 5 (7 x - 4)

= 3 x (7 x - 4) + 5 (7 x - 4)

Factor out common term

7 x - 4

= (7 x - 4) (3 x + 5)

- 2 x^{2} + 36 x + 138 = 0

12 x^{2} + 23 x y - 24 y^{2}

x + 3 < 4

3 (w + 1) + 2 w = 5 (w - 1) + 5

∣ v ∣ \geq 2
