Answer:
(f-g)(x)=-x^(2)+2x+8
the solutions are:
<em><u>x=4 or x=-2</u></em>
Step-by-step explanation:
(f-g)(x)=2x+1-(x^(2)-7)
(f-g)(x)=-x^(2)+2x+1+7
(f-g)(x)=-x^(2)+2x+8
does this help or should I solve for the zeros/solutions of this quadratic equation?
then:
-x^(2)+2x+8=0
-(x^(2)-2x-8)=0
x^(2)-2x-8=0
(x-4)(x+2)=0
<em><u>x=4 or x=-2</u></em>
Step by step explanation:
9
+6x+5=0
Uses the "a", "b", and "c" from "a + bx + c", where "a", "b", and "c" are numbers
So in this case:
a would be 9
b would be 6
c would be 5
Then plug in from there..
Another way you can do it is using the square method.
