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.

3x 2 − 2 = - 5x

Answer 1

Answer:

b = 5

Step-by-step explanation:

All quadratic equations are formed in the format of $a^{2}$ + bx + c = 0

Using this formula, we can re-arrange the equation to fit the given format.

$3x^{2}$ - 2 = -5x
$3x^{2}$ + 5x - 2 = 0

5 is plugged in for "b" in this equation, therefore b = 5.
