Solve each quadratic equation. 4x²=100

4x^2=100
Square root 4x^2=square root 100
4x=plus or minus 10
4x/4=plus or minus 10/4
X= -2.5, x= 2.5

X=100/4
x=25
the square root of 25 is 5
that means x=5

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
