Can someone check my answer please ? Use the quadratic formula to solve the equation x^2-7x-6=0. for my answer i got 7+sqrt73/2 or 7-sqrt73/2

OpenStudy (anonymous):

correct (you divide the whole number by 2 and not just the square root)

OpenStudy (anonymous):

(7+sqrt(73))/2 or x = (7-sqrt(73))/2 so i write it like this?

OpenStudy (anonymous):

yes!

Okay, thank you !(:
