C)	1 real solution

anonymous · Answer

B

anonymous · Answer

t(7t-8)=0
t = 0, 8/7
two real solutions

anonymous · Answer

the only possible way for it to have complex solutions is for it to have a constant term.

because the quadratic formula contains :

$$\sqrt{ b^2-4ac} $$

the only way for the part under the sqrt to be negative is for the expression to have a constant term

if it just have x^2 and x then you just factor out x easy

and if it doesnt have a x^2 then its not a quadratic, its a linear equation , and they can only have one soln
