Complete the following statements in relation to the third term in the expansion of the binomial (2x+y^2)^5
lana [24]
We want to expand (2x + y²)⁵.

From Pascal's Triangle (shown below), the coefficients of the expansion are
1,5,10,10,5,1.

n=0:                        1
n=1:                      1      1
n=2:                   1    2     1
n=3:                 1   3    3     1
n=4:               1   4   6    4     1
n=5:             1   5  10  10   5     1

Therefore the third term in the expansion is 
10*(2x)³*(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴

Alternatively, the third term is
₅C₃ (2x)³(y²)² = 10*(8x³)*(y⁴) = 80x³y⁴

Answer: 80x³y⁴

2. Are the expressions -5 + -2 and -5 – 2 equivalent? Why or why not? Explain and show your work.
scoray [572]

Answer:

Yes, the expressions are equivalent.

Step-by-step explanation:

Notice that -2  is defined as in additive inverse of 2, that is, 2 + -2 = 0.

and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.

Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2
