Solve each equation by graphing the related function. if the equation has no real-number solution, write no solution . 1: x^2+ 7=0 2: 3x^2=0 3: 1/4x^2 - 4=0 4: 4g^2=25

See each answer below.

1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.

2) Dividing by 3 and taking the square root gives an answer of 0.

3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.

4)  Divide by 4 and then take the square root. You have positive or negative 5/2.
