x squared -7x+4+=0

Question

x²-7x+4+=0

Answer 1

You need to use the quadratic formula 

for this since it is not factorable and since completing the square would be messy in this case. 

 

x² - 7x + 4 = 0

a= 1

b= -7

c= 4

 

plugging that into the quadratic formula would give 

 

x =   (7 ± √33)/2

 

If you need the two answers in decimal format, you can plug the numbers into a calculator.
