No it is not.

It means find the value of the expression. It cannot be simplified in the way that algebraic expressions usually are.

x to the third power plus 7

-7p2 -2p3 + 5 is an expression, not an equation or inequality. An expression cannot be solved

++ is an operator that increments the operand. The value of the operand in the expression is incremented first if the ++ is before the operand. The value of the operand in the expression is the same value if the ++ is after the operand.

x3 + 5x2 + 2x - 8It's a third-order polynomial in 'x'.Its value depends entirely on the value of 'x', and whenever 'x' changes,the value of the whole polynomial instantly changes.

x3 + 3x + 5x + 15That's a third-degree expression in 'x'.It can be cleaned up a little bit, by adding the 3x and the 5x. Doing thatdoesn't change anything; it only makes the expression neater:x3 + 8x + 15Now it's a third-degree trinomial in 'x'. If anybody wants to know what numberthe expression is equal to, they'll have to tell you what number 'x' is first. Thevalue of the whole expression depends on the value of 'x', and every time 'x'changes, the value of the expression changes.Notice that it's not an equation, it doesn't ask any question, and it has nosolution or 'answer'. It's just a number, the value of which can be anything.

It's 32 + 24

It is 25.

It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.

It is a quadratic expression which when factored is (2y+3)(y+5)

The answer is 258x

The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.

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

It's an expression, whose exact value depends on the value assigned to "x".

It is: (81*9*64)+19 = 46,675

It's a third-degree polynomial with four terms. The number it represents completely depends on the value of 'x', and even that doesn't tell you much, because if 'x' changes, then the value of the whole expression also changes, in a flash.
