User: Which trinomial is the product of the binomials (2x – y)(x + 3y)?

Weegy: FOIL (First Outside Inside Last) = 2x(2x) + 2x(-3y) + (-3y)(2x) + (-3y)(-3y) = 4x^2 + (-6xy) + (-6xy) + (9y^2) = 4x^2 - 12xy + 9y^2

(2x – y)(x + 3y)

= 2x^2+5xy-3y^2

Subtract the following trinomials: (6x2 + x + 4) - (x2 - x + 9). User: (6x2 + x + 4) - (x2 - x + 9)
Weegy: the answer is D. (3x-4)(2x+5) well, when u solve this kind of problems, u can check the answer by multiplying the FACTORS. here, (3x-4)(2x+5)=6x2 + 7x - 20 however, while solving it, the steps r as follows:- 1. first u multiply 6 with 20. [ This gives 120 2.now, u try to find two numbers, which are factors of 120, and give the difference of 7. here, they r 15 n 8. 3. then u do it as, 6x2 + 15x-8x - 20 =3x(2x+5)-4(2x+5) =(3x-4)92x+5) ] (More)

(6x^2 + x + 4) - (x^2 - x + 9)
= 6x^2 + x + 4 - x^2 + x - 9
= 5x^2 + 2x - 5

(x^3 - x - 4) - (x^2 + x - 4)

= (x^3 - x - 4) + (-x^2 - x + 4)

= x^3 - x^2 - 2x
Factor: x2 + 26x - 56.

x^2 + 26x - 56 = (x + 28)(x - 2)
