Solve each equation by graphing the related function. If the equation has no real-number solution, write no solution.

NOTE: when I write + it has a minus on the bottom too

x^2+7=0

a. x= +7
b. x = +3.5
c. x= 0
d. no solution ***

3x^2=0
a. +3
b. +1/3
c. 0 ***
d. no solution

1/4x^2-4=0

a. x=+3
b. x=+4 ***
c. x=+2
d. no solution

Solve each equation by finding square roots. If the equation has no real-number solution, write no solution.

4g^2=25
a. g=+1/2 ***
b. g=+1/3
c. g=+5/2
d. no solution

64b^2=16
a. b=+1/4
b. b=+1/2
c. b=+1/8 ***
d. no solution

144-p^2=0
a. p=+14
b. p=+6
c. p=+12 ***
d. no solution

5z^2-45=0
a. z=+3
b. z=+1/3
c. z=+9
d. no solution ***

Tell how many solutions this equation has
h^2=-49
a. one solution ***
b. two solutions
c. no solution

s^2-35=-35
a. one solution
b. two solutions ***
c. no solution

Some are ok. I have listed the errors below

--> 4g^2=25

--> 64b^2=16

--> 5z^2-45=0
5z^2 = 45
z^2 = 9
z = ±3

--> h^2=-49

--> s^2-35=-35
s^2 = 0
...

Are you trying to take shortcuts in your head? These are all pretty straightforward, if you just take the proper steps.
