x2−5x+4=0x2-5x+4=0
Subtract 44 from both sides of the equation.
x2−5x=−4x2-5x=-4
To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of bb, the coefficient of xx.
(b2)2=(−52)2(b2)2=(-52)2
Add the term to each side of the equation.
x2−5x+(−52)2=−4+(−52)2x2-5x+(-52)2=-4+(-52)2
Simplify the equation
x2−5x+254=94x2-5x+254=94
Factor the perfect trinomial square into (x−52)2(x-52)2.
(x−52)2=94(x-52)2=94
Solve the equation for xx.
x=4,1x=4,1
