The difference of two trinomials is x2 − 10x + 2. If one of the trinomials is 3x2 − 11x − 4, then which expression could be the

bulgar [2K]

Answer: $4x^2-21x-2$ .

Step-by-step explanation:

Given: The difference of two trinomials is $x^2 -10x + 2$ . If one of the trinomials is $3x^2 - 11x - 4$ .

Then, the other trinomial will be ( $3x^2 - 11x - 4$ ) + ( $x^2 -10x + 2$ )

$=3x^2-11x-4+x^2-10x+2\\\\=3x^2+x^2-11x-10x-4+2\\\\=4x^2-21x-2$

Hence, the other trinomial could be : $4x^2-21x-2$ .
