Can someone explain me this i don't understand?

this equation will be in standard form if you subtract 6x^2 from both sides, add 30 to both sides and subtract 2x from both sides?
6x^2+2x-30=4x^2+9x

a: true
b: false

6x²+2x-30-6x²+30-2x = 4x²+9x-6x²+30-2x
0=-2x²+7x+30
Now we got -2x²+7x+30=0 this is standard form, so answer is A. True

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
