Final answer:
To find an equation equivalent to 7x² + 28x - 33 = 0, we can use factoring to solve the equation and find the values of x.
Step-by-step explanation:
To find an equation equivalent to 7x² + 28x - 33 = 0, we first need to solve the given equation.
Using factoring, the equation can be rewritten as (x-1)(7x+33) = 0. This gives us two possible solutions: x = 1 or x = -33/7.
Therefore, the answer is none of the given options.
