I don't understand plz help! Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. gh

2. g2 - h

3. g + h2

4. g + h

5. h - g

6. g - h

-10. 46. 10. 2. -4. -21

idk

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
