Two students, Carlos and Sophie, factored the trinomial -4x2 − 10x + 6. Sophie factored it as -2(2x − 1)(x + 3) and Carlos facto
damaskus [11]

Sophie has factored the term completely while Carlos has not factored the term completely.

Step-by-step explanation:

We need to factor the trinomial:

-4x^2-10x + 6

Factoring:

-4x^2-10x + 6\\Taking\,\,-2\,\,common:\\-2(2x^2+5x-3)\\Now\,\,factoring:\\-2(2x^2+6x-x-3)\\-2(2x(x+3)-1(x+3))\\-2(2x-1)(x+3)

So, the factored form of -4x^2-10x + 6 is -2(2x-1)(x+3)

So, Sophie has factored the term completely. The terms are factored when we cannot further simplify it. Since Carlos factored (x+3)(-4x+2) 2 can be taken common from the term (-4x+2) so, it is not factored completely.

Please help and please make sure it’s right
slamgirl [31]

Answer:

135 degrees

Step-by-step explanation:

all the angles in a triangle need to add to 180 degrees, so you take

180-(65+70)= 45

Then you just find the supplementary angle

45+x=180

x=135
