Question

Which equation is equivalent to 7x² + 28x - 33=0?

a. (x-2)²=1
b. (x-2)² = 28
c. (x + 2)²= 60/8
d. (x + 2)² = 61/7

Answer 1

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.
