An equation has an equals sign. This does not have one, so it is not an equation and cannot be "solved." It is also unclear what you mean by the expression: the expression, as written, cannot be simplified. Please use parentheses to indicate where the numerator and denominator begin and end.

im guessing that is equal to 0...

i think you could start by multiplying the equation by x:

x^3 + 4x^2 + 9x - 49 = 0

Then I guess you could try factoring, but I couldn't figure out two binomials. Try inserting the equation into a graphing calculator if you have one, and then find the zero.

In school we learnt BODMAS, that is,

Brackets / Division, Multiplication / Addition, Subtraction.

So you do the division or multiplications first.

So, x*x = x squared.

X squared + 4x + (49 divided by x) + 9.

Hope that helps.

Do you mean factor?

Because you can't solve an equation unless it is equal to something.

Its not that hard just use order of operations and combine like terms

no equals sign. its not an equation. no parenthese, not sure whats being divided by what...

not sure what your question is
