Question

Multiple (3×-1) (-×+4)​

Answer 1

12 I cant explain cuz it goes over and over Lol

Answer 2

`\large\boxed{-3x^2+13x-4}`

Explanation:

Use FOIL:

(a + b)(c + d) = ac + ad + bc + bd

`(3x-1)(-x+4)=(3x)(-x)+(3x)(4)+(-1)(-x)+(-1)(4)\\\\=-3x^2+12x+x-4\\\\\text{combine like terms}\\\\=-3x^2+(12x+x)-4=-3x^2+13x-4`
