factor-a^3+11a^2-39a+45

factor

- a^{3} + 11 a^{2} - 39 a + 45

- (a - 3)^{2} (a - 5)

Solution steps

- a^{3} + 11 a^{2} - 39 a + 45

Factor out

- 1 : - (a^{3} - 11 a^{2} + 39 a - 45)

= - (a^{3} - 11 a^{2} + 39 a - 45)

Factor

a^{3} - 11 a^{2} + 39 a - 45 : (a - 3) (a - 3) (a - 5)

= - (a - 3) (a - 3) (a - 5)

Apply exponent rule:

aa = a^{2}

(a - 3) (a - 3) = (a - 3)^{2}

= - (a - 3)^{2} (a - 5)

\frac{2}{x + 1} \leq \frac{1}{x - 2}

(x - 2)^{2} \geq 0

(k - 2) (k - 1) = - 1

(- 33)^{2}

- \frac{11}{4} (\frac{11 x}{3} - \frac{15}{4}) \geq \frac{415}{8} + x
