What is the value of the expression x-y squared when x equals 7 and y equals negative 2?
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
What is 2x plus 5?
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.

What is the value of n in the expression x cubed plus nx squared plus 3x -5 when divided by x -2 with a remainder of -3 showing brief details of your work?
Use the remainder theorem:- f(x) = x3+nx2+3x-5 f(x) becomes f(2) because the divisor is x-2 and 2-2 = 0 f(2) = 8+4n+6-5 = -3 f(2) = 4n+9 = -3 f(2) = 4n = -12 f(2) = n = -3 So the value of n in the expression is -3 Check: f(2) = 8+(4*-3)+6-5 = -3
