factor 21y^2+23y-20

factor

21 y^{2} + 23 y - 20

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

Solution steps

21 y^{2} + 23 y - 20

Break the expression into groups

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

Factor out

3 y

from

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

Factor out

5

from

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

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

Factor out common term

7 y - 4

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

x^{3} - 5 x^{2} - 9 x + 45

\frac{3 x + 5}{x ^{2} + 2 x - 35} \geq 0

\frac{1 - ( 2 ) ^{2}}{( 1 + ( 2 ) ^{2} ) ^{2}}

9 x^{2} - 3 x - 6

\frac{1}{5} \cdot \frac{1}{5}
