Question

(3k+4) (8k-5) equation

Answer 1

Answer: 24k² + 17k - 20

Explanation:

Our task is to simplify the following:

`\bullet\quad\sf{(3k+4)(8k-5)}`

We're going to use a technique called FOIL.

(FOIL = first, outer, inner, last)

Multiply the first terms: 3k * 8k = 24k^2

Multiply the outer terms: 3k * (-5) = -15k

Multiply the inner terms: 4 * 8k = 32k

Multiply the last terms: 4 * (-5) = -20

Result : 24k² - 15k + 32k - 20

Combine like terms: 24k² + 17k - 20

Answer 2

`(3k+4)(8k-5)\\\\= 24k^(2) +32k-15k-20\\\\= 24k^(2) + 17k -20`
