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!
