Answer:
=1+√6 or x=1−√6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x²−2x=5
Step 2: Subtract 5 from both sides.
x²−2x−5=5−5
x²−2x−5=0
For this equation: a=1, b=-2, c=-5
1x²+−2x+−5=0
Step 3: Use quadratic formula with a=1, b=-2, c=-5.
x= −b±√b²−4ac /2a
x= −(−2)±√(−2)²−4(1)(−5) /2(1)
x= 2±√24 /2
x=1+√6 or x=1−√6
