Find the product and simplify

(X-4) (3x-y)

(x-4) (3x - y)

multiply the first X with the other two terms in the other paranthesis

so x * 3x and x * - y

and ull get

3x^2 - xy

now multiply the - 4 with the two terms of other paranthesis

so - 4 * 3x and - 4 * - y

and u get - 12x and 4y

cant simpligly so

3x^2 - xy - 12x + 4y
