Write the quadratic equation whose roots are 2 and -6, and whose leading coefficient is 2.

f(x) = 2x^2 +8x - 24

Step-by-step explanation:

Let's use the clues:

roots are 2 and -6  in factor form will be

(x-root1) ( x-root2) = (x-2)(x+6) = x^2 +6x -2x-12= x^2 +4x -12

But the leading coeficient here is 1 and we needet to be 2 so just mltiply the whole eq. by 2

2 (x^2 +4x -12) = 2x^2 +8x - 24

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
