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
Answer:
The first one and the second one.
Step-by-step explanation:
Answer:
The answer is 2145$
Step-by-step explanation:
825×0.04=33
Once every quarter of a year means the number of years × 4 = 10×4=40
So
33×40 =1320$
1320+825=2145$
