Question

In algebra determine the nature of the solutions of the equation 7t^2-8t=0
Choose the solution
A) 2 imaginary solutions
B) 2 real solutions
C) 1 real solution

Answer 1

B

Answer 2

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

Answer 3

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

Answer 4

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
