To find the solutions to the quadratic equation 2x^2 - 5x = 6, we can set the equation equal to zero and solve for x.
2x^2 - 5x - 6 = 0
To factorize the equation, we need to find two numbers whose product is -12 (-6*2) and whose sum is -5. The numbers are -6 and 2.
2x^2 - 6x + 2x - 6 = 0
2x(x - 3) + 2(x - 3) = 0
(2x + 2)(x - 3) = 0
Setting each factor equal to zero, we get:
2x + 2 = 0 --> 2x = -2 --> x = -1
x - 3 = 0 --> x = 3
So the solutions to the equation are x = -1 and x = 3.
Among the given options, the solution to the quadratic equation is:
x = -1.03
