What is y^2-7y+6=0 and you have to solve for y
2 answers:
Y^2 - 7y + 6 = 0
(y - 1)(y - 6) = 0
y - 1 = 0
y = 1
y - 6 = 0
y = 6
so y = 1 or y = 6
There are several different methods you could use to solve y^2=7y+6=0. One is to factor and then to set each factor = 0 and solve for y in each case:
(y-6)(y-1)=0 yields the equations y-6=0 and y-1=0. Solve these two equations for the two roots.
Another approach would be to apply the quadratic formula. Here a=1, b=-7 and c=6.
