x^2+x-2>0

Solution

x^{2} + x - 2 > 0

Solution

x < - 2 or x > 1

+1

Interval Notation

(- \infty, - 2) \cup (1, \infty)

Solution steps

x^{2} + x - 2 > 0

Factor

x^{2} + x - 2 : (x - 1) (x + 2)

(x - 1) (x + 2) > 0

Identify the intervals

x < - 2 or x > 1

Popular Examples

1.3*10^9= 1/2*8.2*10^4*x^2

1.3 \cdot 1 0^{9} = \frac{1}{2} \cdot 8.2 \cdot 1 0^{4} \cdot x^{2}

2 = 6 x - 10

11 = \frac{c}{- 5} + 8

x^{2} - 7 x + 3 = 0

domain of f(a)=(4a^2-36a)/(2a^4-24a^3+54a^2)domain

f (a) = \frac{4 a ^{2} - 36 a}{2 a ^{4} - 24 a ^{3} + 54 a ^{2}}
