Question

this is my last question of the day, I promise, LOL! Is this right..(2x-1)(x+2) = 2^2+4x-1x-2?

Answer 1

yeah that is right,
you just left of the x in the first term on the right hand side (before the ^2)
\[(2x-1)(x+2) = 2x^2+4x-1x-2\]
but that is a typographical error not a mathematical error
you got it right

Answer 2

Yep. 2x^2 +3x -2

Answer 3
