8. if you were going to use the quadratic formula to solve the following equation and a = 9, what number would you use as the value for the variable 'b'? 3x + 8 = 9x2 the variable 'b' = (4.0 points) part 9 - - 0/1 answered questions, 4.0 points

Remember, for solve the quadratic equation

we use the quadratic formula

We have the equation since a must be 9 then we pass the entire left side of the equation to the right side. We get the equation:

Then, observe that a=9 and b=-3

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

the answer is a
