Iam timed ): part a: show all work to solve the quadratic equation x2 + 2x − 15 = 0 by factoring. (2 points) part b: using complete sentences, explain what the solutions from part a represent on the graph. (2 points)

If you are talking about x factoring then, there would be 2, zeros.

Step-by-step explanation:

put -15 at the top of the X, and 2 at the bottom. The 2 numbers that multiply to -15 and add to 2, are 5 and -3. Then make those (x+5)(x-3)=0. Then the signs change because

X+5=0, move the 5 to the other side which equals , x=-5

x-3=0, move the 3 over to the other side, which equals x=3.

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400
