Answer:
See solution
Step-by-step explanation:
Use formula for the binomial expansion:
Note that
1. For the expression
2. For the expression
3. For the expression
4. For the xpression
5. In the expansion of each term has the degree of 8. Since product has degree 2+3=5, this term is not possible. Since product has degree 1+8=9, this term is not possible. Similarly, term has degree 6+5=11 and is not a term of expansion Products have degree 8 (5+3=8=4+4=8=1+7), these products are possible terms with corresponding coefficients.
Answer:
73
Step-by-step explanation:
I think you mean the discriminant.
You calculate it by using b^2 - 4ac
a = 2
b = 7
c = -3
So it would be 49 - 4 * 2 * -3
49 + 24
73
