factor x^2+6x-40

factor

x^{2} + 6 x - 40

(x - 4) (x + 10)

Solution steps

x^{2} + 6 x - 40

Break the expression into groups

= (x^{2} - 4 x) + (10 x - 40)

Factor out

x

from

x^{2} - 4 x : x (x - 4)

Factor out

10

from

10 x - 40 : 10 (x - 4)

= x (x - 4) + 10 (x - 4)

Factor out common term

x - 4

= (x - 4) (x + 10)

2 x^{2} + x (- \frac{x}{2}) + (- \frac{x}{2})^{2} = 4

3 ln (10) + 2 ln (100)

27 x^{3} - 343 y^{3}

4 y^{2} - 2 y - 12

r^{3} + 8 b^{3}
