Question

solve quadratic equation. t^2=-3t+4

Answer 1

t^2 + 3t - 4 = 0
(t+4)(t-1)=0
t=-4 or t=1

Answer 2

correct

Answer 3

t^2 +3t -4 =0
(t+4)(t-1)=0

Answer 4

so I set it to zero and go from there. how do I determine if it has any real roots

Answer 5

the real roots are t+4=0 --- so t=-4 and t-1=0 so t=1

Answer 6

That is what I though but had to makesure Thanks all
