Answer 1

`(4x - 3)(5x - 8) = 20x^2 -47x + 24`

Explanation:

Given

`(4x - 3)(5x - 8)`

Required

Identify and correct error

The error is when the inner and outer terms are multiplied. i.e.

`4x * -8 = -32x` not 32x

`-3 * 5x = -15x` not 15x

So, the expression is:

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

`(4x - 3)(5x - 8) = 20x^2 -47x + 24`
