Answer:
Step-by-step explanation:
Ex 1 : B
Ex 2; B
Ex 3; D
Point slope form- y-4=(x+2)
Slope intercept- y=x+6
You multiply the binomial by the whole trinomial.
So 5x^2 (5x^3 - 6x^2 - 5) and then -2x (5x^3 - 6x^2 - 5)
then solve so it is:
25x^5 - 30x^4 - 25x^2 - 10x^4 + 12x^3 + 10x.
Then you simplify to:
25x^5 - 40x^4 + 12x^3 - 25x^2 + 10x
