Question

If -1 and 3 are the roots of x2 + px + q = 0,
find the values of p and Q​

Answer 1

Let's solve for p.

x2+px+q=0

Step 1: Add -x^2 to both sides.

px+x2+q+−x2=0+−x2

px+q=−x2

Step 2: Add -q to both sides.

px+q+−q=−x2+−q

px=−x2−q

Step 3: Divide both sides by x.

pxx=−x2−q

xp=−x2−qx

Answer:

p=−x2−qx

Answer 2

Answer:

p=-2 q=-3
