Question

Perform the operation:

(2x4 + 5x3 + 8x +24) ÷ (x + 2)

Answer 1

53

Explanation:

We can solve the bits in the operation like this...starting with

2x4 = 8

+

5x3 = 15

(we can skip over 8x for now and add the next number)

+

24

= 8+15+24

= 47

so now we have:

(47+8x) ÷ (x+2)

let's get rid of the numbers on the right side, so we subtract 2 from both sides. now we have

(45+8x) ÷ (x)

now we want our x on the left to move to the x on the right, so we'll divide everything by x

we get (45+8) ÷ x/x which = (53) ÷ x/x and we know x/x = 1, so we have

53 ÷ 1, and that = our answer, which is 52
