Question

What are solutions to this equation, x^2 + 3x -4 >0

Answer 1

Solution of equation :-

x = 1 or x = -4

Explanation:

The given quadratic equation is x² + 3x - 4 = 0

To find the solution

Using splitting method

x² - x + 4x - 4 = 0

x(x - 1) + 4(x - 1) = 0 (take x and 4 as common)

(x - 1)(x + 4) = 0

(x - 1) = 0 or (x + 4)= 0

If x - 1 = 0 then x = 1

If x + 4 = 0 then x = -4
