Answer:
Step-by-step explanation:
x^2-9x=-2 move the -2 over and set to 0
x^2-9x+2=0
This can not be factored, so use the quadratic formula.
x=9±√73 /2
Answer:
x = 9 + sqrt(73) / 2
x = 9 - sqrt(73) / 2
Step-by-step explanation:
Assuming you want to factor and find its roots:
[Put all the terms in the left hand size]
x^2-9x+2=0
[Use the quadratic formula; Not factorable and too tedious for completing the square]
x = -b +- sqrt(b^2-4ac) / 2a
x = 9 + sqrt(9^2 - 4(1)(2)) / 2(1)
x = 9 - sqrt(9^2 - 4(1)(2)) / 2(1)
x = 9 + sqrt(73) / 2
x = 9 - sqrt(73) / 2
