Hey mate! Here's your answer:
Step-by-step explanation:
2x² + 4x - 198 = 0
x² + 2x - 99 = 0
Now, we have to get 2 numbers whose sum is 2 and product is -99.
Those two numbers are 11 and -9.
x² - 9x + 11x - 99 = 0
x(x - 9) + 11(x - 9) = 0
(x + 11)(x - 9) = 0.
Now,
x + 11 = 0
x = -11.
x - 9 = 0
x = 9.
So the two solutions to this Quadratic Equation are x = -11 and x = 9.
