factor 3x^3-12x^2-45x

factor

3 x^{3} - 12 x^{2} - 45 x

3 x (x^{2} - 4 x - 15)

Solution steps

3 x^{3} - 12 x^{2} - 45 x

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

x^{2} = xx

= 3 x^{2} x - 12 xx - 45 x

Rewrite

12

3 \cdot 4

Rewrite

45

3 \cdot 15

= 3 x^{2} x - 3 \cdot 4 xx - 3 \cdot 15 x

Factor out common term

3 x

= 3 x (x^{2} - 4 x - 15)

(12 x + 3)^{- 1} < 0

4 (x + 3) - 4 = 8 (\frac{1}{2} x + 1)

(33)^{2}

x + 2 x + 3 x = - 76

a, 4 + a_{n - 1} a_{1} = 2
