Question
If one wanted to solve the equation below using the quadratic formula, what would be the b value used to substitute into the quadratic equation. 2x 2 + 9 = −6x
Solution
The equation given is 2x^2 + 9 = -6x.
First, we need to rearrange the equation into the standard form of a quadratic equation, which is ax^2 + bx + c = 0.
So, we rearrange the given equation to: 2x^2 + 6x + 9 = 0.
In this equation, the coefficient of x (which is the 'b' value in the quadratic formula) is 6.
