Answer 4

\[x^2-7x+12=0\]Can either factor or might be just as easy to use the quadratic equation.\[ax^2+bx+c=0\]\[x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}\]

Answer 5

apply the concept correctly

Answer 6

Add 12 to both sides.

\(\Large \color{MidnightBlue}{\Rightarrow x^2 - 7x + 12 }\)

A quadratic equation is ax^2 + bx + c = 0
According to that, the formula is:

\(\Large \color{MidnightBlue}{\Rightarrow x = {-b \pm \sqrt{b^2 - 4ab} \over 2a} }\)
