1517x2
1517x2−7=0
Move the constant to the right-hand side and change its sign
1517x2=0+7
Removing 0 doesn't change the value,so remove it from the expression
1517x2=7
Divide both sides
15171517x2=15177
Divide the numbers
x2=15177
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±15177
