The product of a binomial and trinomial is x^3+3x^2-x+2x^2+6x-2 which expression is equivalent to this product after it has been
fully simplified?
1 answer:
Answer: First option.
Step-by-step explanation:
You know that the product obtained by multiplying a binomial and a trinomial is:
Then, in order to simplify this product, it is necessary to add the like terms.
Therefore, the expression that is equivalent to this product after it has been fully simplified is:
You can observe that this matches with the first option.

Step-by-step explanation:
In the triangle JKL, the sides can be calculated as following:
- J(2;5); K(1;1)
=> JK =
- J(2;5); L(5;2)
=> JL =
- K(1;1); L(5;2)
=> KL =
In the triangle QNP, the sides can be calculate as following:
- Q(-4;4); N(-3;0)
=> QN =
- Q (-4;4); P(-7;1)
=> QP =
- N(-3;0); P(-7;1)
=> NP =
It can be seen that QPN and JKL have: JK = QN; JL = QP; KL = NP
=> They are congruent triangles
