Find the value or values of y in the quadratic equation y2 + 4y + 4 = 7.

If we move 7 to one side, we have (y^2 + 4y - 3) = 0. From this form, we can apply the quadrati formula to solve for the values of y. To recall, quadratic formula is [ - b ±√ (b² - 4ac) ]/2a. For our equation, we have a = 1, b = 4, and c = - 3. If we plug this in, we have y to have approximate values of - 2 - sqrt (7) and - 2 + sqrt (7).
