X²+3x-21=0
1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2
2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21
Answer: the product of the 2 solutions of this equation is -21

I only see one question.
The answer is the root 4 has the multiplicity of 2.
9/16+1/2 is the same thing as 9/16 + 8/16 so lets use that. and that =17/16 which when simplified is = 1 1/16
Hope it helps!
