Question

What are the solutions of the quadratic equation x² - 7x = -12?a. 3 and 4b. -2 and -6c. 2 and 6d. 3 and 4e. -3 and -4

Answer 1

Given the following quadratic equation:

$x²-7x=-12$

We will rewrite the equation in the standard form as follows:

$x^2-7x+12=0$

Factor the equation:

$(x-3)(x-4)=0$

Find the zeros of the equation:

$\begin{gathered} x-3=0\rightarrow x=3 \\ x-4=0\rightarrow x=4 \end{gathered}$

So, the answer will be option a. 3 and 4
