The answer is 2/3 hope this helps
/ = fraction
(3x + 2y)³
(3x + 2y)(3x + 2y)(3x + 2y)
27x³ + 18x²y + 18x²y + 12xy² + 18x²y + 12xy² + 12xy² + 8y³
27x³ + 54x²y + 36xy² + 8y³
Answer:
b=20 or b=-20
Step-by-step explanation:
Keep in mind the meanings of the values of the discriminant:
If b^2-4ac=0, then the quadratic will have only 1 solution (double root)
If b^2-4ac<0, then the quadratic will have no real solutions
If b^2-4ac>0, then the quadratic will have 2 unique solutions
In this case, to get one real solution, the discriminant must be set up as b^2-4ac=0. Setting up the equation we get:
b^2-4(4)(25)=0
b^2-400=0
b^2=400
b=20 or b=-20
So the values of b would have to be either 20 or -20
