This depends where the brackets go. If the equation you want to simplify is (2x)(x2) + 9 then we just multiply the parts in the brackets. When you multiply powers you add the power, so this is 2x3+9
If the equation is 2x(x2+9) then we need to multiply each part of the bracket by 2x. This gives 2x3+18x
That can't be simplified.
negative eight plus two times four to the second power

simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34

-2 times -2 = plus 4 since minus times minus is plus
It is 37,500.
It means find the value of the expression. It cannot be simplified in the way that algebraic expressions usually are.
36 times 10^3 plus fifteen times 10^2 is equal to 37,500.
x3-5x2+x is already simplified.
