Answer 2

Answer:

Step-by-step explanation:

9-3x^2=3

We move all terms to the left:

9-3x^2-(3)=0

We add all the numbers together, and all the variables

-3x^2+6=0

a = -3; b = 0; c = +6;

Δ = b2-4ac

Δ = 02-4·(-3)·6

Δ = 72

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:
