There will always be two solutions.

anonymous · Answer

for both?

anonymous · Answer

yes

anonymous · Answer

any quadratic equation have two and only two solutions

anonymous · Answer

Oh Ok. Thank you.

1. there is 1 solution but its called a repeated solution

x^2 - 8x + 16 = (x-4)^2

2. rewrite the quadratic

x^2 + 9x - 7 = 0

this will have two unequal solutions but it needs the general quadratic formula to find the solutions
