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.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

move it to the other side
