(3x - 1)(x +4)= = 3x * x + 3x * 4 - 1 * x - 1 * 4 = = 3x^2 + 12x - x - 4 = = 3x^2 + 11x - 4
The trinomial equivalent to ( 3 x − 1 ) ( x + 4 ) is 3 x 2 + 11 x − 4 . This is found by using the distributive property and combining like terms. The steps involve carefully multiplying and summing the terms from both binomials.
