factor x^3+7x^2-4x-28

factor

x^{3} + 7 x^{2} - 4 x - 28

(x + 7) (x + 2) (x - 2)

Solution steps

x^{3} + 7 x^{2} - 4 x - 28

= (x^{3} + 7 x^{2}) + (- 4 x - 28)

Factor out

x^{2}

from

x^{3} + 7 x^{2} : x^{2} (x + 7)

Factor out

- 4

from

- 4 x - 28 : - 4 (x + 7)

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

Factor out common term

x + 7

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

Factor

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

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

- 57 x + 57 = - 75 x + 75

lo g_{1.09} (3.34) = 1 t

x^{2} - 2 x + 5

a^{2} - 81

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