4×2-10=26
Add 10 to both sides of the equation.
4×2=26+10
Add 26 and 10.
4×2=36
4×2=36
Divide each term in 4×2=36 by 4.
4×24=364
Cancel the common factor of 4.
Cancel the common factor.
4×24=364
Divide x2 by 1.
x2=364
x2=364
Divide 36 by 4.
x2=9
x2=9
Take the square root of both sides of the equation to eliminate the exponent on the left side.
x=±9
Simplify the right side of the equation.
Rewrite 9 as 32.
x=±32
Pull terms out from under the radical, assuming positive real numbers.
x=±3
x=±3
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the ± to find the first solution.
x=3
Next, use the negative value of the ± to find the second solution.
x=-3
The complete solution is the result of both the positive and negative portions of the solution.
x=3,-3
x=3,-3
x=3,-3
Solve using the Square Root Property 4x^2-10=26
