Question

Simplify 3x3+27×2-15x÷3x

Answer 1

`\bf 3x^3+27x^2-15x/ 3x\implies \cfrac{3x^3+27x^2-15x}{3x}\implies \stackrel{\textit{distributing the denominator}}{\cfrac{3x^3}{3x}+\cfrac{27x^2}{3x}-\cfrac{15x}{3x}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill x^2+9x-5~\hfill`

Answer 2

63-5x

So you do PEMDAS

There aren’t any parenthesis

There aren’t any exponents

So you multiply 3*3 and get 9

Multiply 27 by 2 and get 54

And divide 15x by 3x

Now moving on to addition/subtraction

The equation is now 9+54-5x

9+54 is 63

So the answer is 63+5x
