The coefficients in the expansion of (x+y)^5 are
a. 0, 5, 10, 10, 5, 0
b. 0, 1, 5, 10, 5, 1, 0
c. 1, 5, 10, 10, 5, 1
d. 1, 5, 10, 5, 1

ANSWER

C. 1, 5, 10, 10, 5, 1

EXPLANATION

We can quickly generate the Pascal's triangle as shown in the attachment.

In general this triangle, the extreme values are always 1.

The inner entries are obtained by adding the two entries directly above them.

From the Pascal's triangle, the coefficients in the expansion of (x+y)^5 are 1, 5, 10, 10, 5, 1

The correct choice is C

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
