Solution

x < - 8 or x > - 5

+1

Interval Notation

(- \infty, - 8) \cup (- 5, \infty)

Solution steps

x^{2} + 13 x > - 40

Rewrite in standard form

x^{2} + 13 x + 40 > 0

Factor

x^{2} + 13 x + 40 : (x + 5) (x + 8)

(x + 5) (x + 8) > 0

simplify ((-4/3)+8)/(4-(-4/3))simplify

\frac{( - \frac{4}{3} ) + 8}{4 - ( - \frac{4}{3} )}

\frac{2}{8} = \frac{v}{12}

∣ x ∣ > - 6

(4x-3)(4x+3)-4(3-2x)^2=3x

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