7x²=9+x
so
for
0=ax²+bx+c

x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}
so

7x²=9+x
mins 9 from both sides and minus x
7x²-1x-9=0
a=7
b=-1
c=-9


x=\frac{-(-1)+/-\sqrt{(-1)^2-4(7)(-9)}}{2(7)}
x=\frac{1+/-\sqrt{(-1)^2+4(7)(9)}}{2(7)}
so the 4th one

Solve for x.
Ostrovityanka [42]

Answer:

C.  3, -7

Step-by-step explanation:

x^2 +4x-21 =0

Factor

What 2 numbers multiply to -21 and add to 4

7*-3 = -21

7-3 = 4

(x+7) (x-3) =0

Using the zero product property

x+7 =0       x-3=0

x+7-7=0-7     x-3+3=0+3

x = -7            x=3
