Solve the equation by using the quadratic formula.
3 x squared minus 1 = 7 x

b.  

Step-by-step explanation:

Quadratic equations are suppose to be written as:

so the new quadratic equation for this problem will be:

Now rearrange the terms:

Then use the Quadratic Formula to Solve for the Quadratic Equation

Quadratic Formula =

Note: Ignore the A in the quadratic formula

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

a = 3

b = -7

c = -1
