Which value of x is a solution to this equation?
2x^2+ 6x -20=0
The solution to this equation can be found by factoring or using the quadratic formula.
Factoring:
2x^2 + 6x - 20 = 0
2(x^2 + 3x - 10) = 0
2(x + 5)(x - 2) = 0
Setting each factor to 0:
x + 5 = 0
x = -5
x - 2 = 0
x = 2
Therefore, x = -5 and x = 2 are the solutions to the equation.
