Question

Find the value of K so that (x+2)(x-3)+2x-1=x^2-2Kx-7

Answer 1

Answer:

k= −1/2

Step-by-step explanation:

Let's solve for k.

(x+2)(x−3)+2x−1=x2−2kx−7

Step 1: Flip the equation.

−2kx+x^2−7=x^2+x−7

Step 2: Add 7 to both sides.

−2kx+x^2−7+7=x^2+x−7+7

−2kx+x^2=x^2+x

Step 3: Add -x^2 to both sides.

−2kx+x^2+−x^2=x^2+x+−x^2

−2kx=x

Step 4: Divide both sides by -2x.

−2kx/ −2x = x/−2x

k= −1/2
