factor 7x^3+3x^2-28x-12

factor

7 x^{3} + 3 x^{2} - 28 x - 12

(7 x + 3) (x + 2) (x - 2)

Solution steps

7 x^{3} + 3 x^{2} - 28 x - 12

= (7 x^{3} + 3 x^{2}) + (- 28 x - 12)

Factor out

x^{2}

from

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

Factor out

- 4

from

- 28 x - 12 : - 4 (7 x + 3)

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

Factor out common term

7 x + 3

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

Factor

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

= (7 x + 3) (x + 2) (x - 2)

\frac{1 6 ^{2}}{2}

\frac{1}{2} bh

∣ 4 x + 3 ∣ - 9 = 3

- 9 x + 7 \geq 25

2 x - 1 > 5
