Answer:
move the -8x to the left side as a +8x
move the 48 as a -48 to the left side
identify a, b, and c.
Step-by-step explanation:
the expression is:
[tex]x^2=-8x+48[/tex]
to be able to plug the values for the quadratic formula, we need all of the terms on one side of the equal sign. Thus the first step is:
move the -8x to the left side as a +8x:
[tex]x^2+8x=48[/tex]
second step:
move the 48 as a -48 to the left side:
[tex]x^2+8x-48=0[/tex]
third step:
identify a, b, and c.
a is the number that accompanies the [tex]x^2[/tex]
[tex]a=1[/tex]
b is the number that accompanies the [tex]x[/tex]
[tex]b=8[/tex]
and c is the indepedent number:
[tex]c=-48[/tex]
Now you are ready to plug these number into the quadratic formula:
[tex]x=\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]
