Question

PLEASE HELP ME I AM SO CONFUSED

Find the discriminant of each quadratic equation then state the number and type of solutions.
7) 4k + 2 =9k
8) 5a² + 2 = 1 - 4a^2 - 6a

Answer 1

For the number 7, begin by solving for k.
Remember your discriminant rules:
k is greater than 0, there are 2 real solutions
k is equal to 0, there is one real solution
k is less than 0, there are no real solutions

On number 8, solve for a, and then figure out the number of solutions using the rules above.

Hope this helps!
