Complete the square to solve the equation below.
x²+x =7/4
a.)x=3, x= -1
b.)x= -2+ √2, x= -2- √2
c.) x= -1/2+√2, x= -1/2- √2
d.) x=1+ √-2, x= 1- √2

Hello there!

x² + x = 7/4
x² + - 7/4 = 0

Now we gonna use the quadratic formula to find x
a= 1
b=1
c = -1.75

x = -b+/-√b² -4ac all of them divide by 2a
x = -(1)+/-√(1)² - (4)(1)(-1.75) all of them divide by 2(1)
x= -1+/-√8 all of them divide by 2
x = -1/2 + √2 or x = -1/2 - √2

The correct option is option C

I hope that helps!

(-0, -7) is your answer
