x^2-2x-15>0

Solution

x^{2} - 2 x - 15 > 0

Solution

x < - 3 or x > 5

+1

Interval Notation

(- \infty, - 3) \cup (5, \infty)

Solution steps

x^{2} - 2 x - 15 > 0

Factor

x^{2} - 2 x - 15 : (x + 3) (x - 5)

(x + 3) (x - 5) > 0

Identify the intervals

x < - 3 or x > 5

Popular Examples

simplify ((8x^{-2}y^{-2}z)/(-x^4y^{-4)z^3})^{-1}simplify

(\frac{8 x ^{- 2} y ^{- 2} z}{- x ^{4} y ^{- 4} z ^{3}})^{- 1}

2 x^{2} - 7 x + 10 = 0

2 x + 2 = 12 - x^{2}

14 \geq - 2 x + 4 \geq - 2

- x^{2} + 16 = 0
