Answer:
The expression (-root3·a - a)², can be simplified into the form a² × (4 + 2·√3)
Step-by-step explanation:
The given expression can be written as follows;
(-root3·a - a)² = (-√3·a - a)²
Which can be expanded to give;
(-√3·a - a) × (-√3·a - a) = 3·a² + 2·√3·a² +a²
We collect like terms to get;
3·a² + 2·√3·a² +a² = 3·a² +a²+ 2·√3·a² = 4·a² + 2·√3·a²
We factorize out the common coefficients of the terms to have;
4·a² + 2·√3·a² = a² × (4 + 2·√3)
Which gives the initial expression (-root3·a - a)², to presented in the form a² × (4 + 2·√3).
Answer: so to give a hint the graph is not porportional bc it does not run through the orgin so there for the equation you have to look at the first dot describe that write down the points and see how far apart they are by dividing them
