Answer:
x = 2 or x = -5
Step-by-step explanation:
x² + 3x - 4 = 6
x² + 3x -4 - 6 = 0
x² + 3x - 10 = 0 (Here you find two numbers that have a sum of 3 and a product of -10. These two numbers would be 5 and -2. 5 - 2=3 and 5×-2 =-10.)
x² + 5x - 2x -10 = 0 (They you replace 3x by 5x and -2x)
(x² + 5x) (-2x -10) =0 - (You find common terms)
x(x + 5) -2(x + 5) = 0
(x - 2) (x + 5) = 0
So
x - 2 = 0 or x + 5 = 0
x =2 x = -5
