x^2-2x-5>3

Solution

x^{2} - 2 x - 5 > 3

Solution

x < - 2 or x > 4

+1

Interval Notation

(- \infty, - 2) \cup (4, \infty)

Solution steps

x^{2} - 2 x - 5 > 3

Rewrite in standard form

x^{2} - 2 x - 8 > 0

Factor

x^{2} - 2 x - 8 : (x + 2) (x - 4)

(x + 2) (x - 4) > 0

Identify the intervals

x < - 2 or x > 4

Popular Examples

7(5x+9)=12-(x+9)

7 (5 x + 9) = 12 - (x + 9)

simplify (36x^{-4}y^2z^0)/(5x^2y^{-3)z^{-2}}simplify

\frac{36 x ^{- 4} y ^{2} z ^{0}}{5 x ^{2} y ^{- 3} z ^{- 2}}

- 0.8 \cdot ln ∣ 1 - x ∣ = 8

7 ∣ 2 x - 1 ∣ = 21

(5y-6)/2 =y-(2-y)/3

\frac{5 y - 6}{2} = y - \frac{2 - y}{3}
