Using Pascal triangle, write down the binomial expansion of
simplifying all the terms.​

1 + 8y + 28y² + 56y³ + 70 + 56 + 28 + 8 +

Step-by-step explanation:

For the expansion of

Using the row of Pascal's triangle for n = 8 , that is the coefficients are

1  8  28  56  70  56  28  8  1

Decreasing powers of 1 from to

Increasing powers of y from to

Then

= 1 . . + 8. . + 28. .y² + 56. .y³ + 70. . + 56. 1³. + 28. 1². + 8. . + 1. .

= 1 + 8y + 28y² + 56y³ + 70 + 56 + 28 + 8 +

Step-by-step explanation:

Given binomial

Expanding using Pascal triangle (attached)

Replace a and b with y and 1 in the bottom row of the triangle

step-by-step explanation:

d

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
