The difference of two trinomials is x2 - 10x + 2. If one of the trinomials is 3x? - 11x - 4, then which expression could be the
klio [65]

Answer:

2x^2-x-6

or

4x^2-21x-2

Step-by-step explanation:

The difference of two trinomials P(x) and Q(x) is x^2 - 10x + 2. This means that

P(x)-Q(x)=x^2-10x+2

or

Q(x)-P(x)=x^2-10x+2

If one of the trinomials is P(x)=3x^2-11x - 4, then

(3x^2-11x-4)-Q(x)=x^2-10x+2

or

Q(x)-(3x^2-11x-4)=x^2-10x+2

1. If (3x^2-11x-4)-Q(x)=x^2-10x+2, then

Q(x)=(3x^2-11x-4)-(x^2-10x+2)\\ \\Q(x)=(3x^2-x^2)+(-11x+10x)+(-4-2)\\ \\Q(x)=2x^2-x-6

2. If Q(x)-(3x^2-11x-4)=x^2-10x+2, then

Q(x)=(x^2-10x+2)+(3x^2-11x-4)\\ \\Q(x)=(x^2+3x^2)+(-10x-11x)+(2-4)\\ \\Q(x)=4x^2-21x-2
