Question

Multiply (3x-1)(-x+4)​

Answer 1

Answer:

$-3x^{2}+13x-4$

Step-by-step explanation:

You can use the foil technique (first outer inner last)

(3x - 1)(-x + 4) = (3x · (-x)) + (3x · 4) + ((-1) · (-x)) + ((-1) · 4)

                      = $-3x^{2}+12x+x-4$

                      = $-3x^{2}+13x-4$
