[ 3x2 - 7x - 20 ] is not a problem, and needs no solution. It's just an expression that
stands for a number, and there's no way to find out what the number is until you know
what number 'x' is.
If you had said that this expression is equal tosomething, then you'd have an equation,
and you could ask us to find what number 'x' must be in order to make the equation a
true statement. But all you have just now is a number, that depends on the value of 'x'.
