Question
Solve the quadratic equation
Solve using the quadratic formula
Solve by completing the square
Solve using the PQ formula
x1=−1065+1329,x2=106−5+1329
Alternative Form
x1≈−0.707615,x2≈0.613275
Evaluate
x−53x2=6x−23
Move the expression to the left side
−5x−53x2+23=0
Rewrite in standard form
−53x2−5x+23=0
Multiply both sides
53x2+5x−23=0
Substitute a=53,b=5 and c=−23 into the quadratic formula x=2a−b±b2−4ac
x=2×53−5±52−4×53(−23)
Simplify the expression
x=106−5±52−4×53(−23)
