4(f2 - g) + (f2 + 2g) which can be expanded and simplified to 5f2 - 2g
That verbal expression would read: 3(x+y)^2 + 5(2x -y) ^2 means 'squared' in the above example.
The expression "4 times x squared" can be written as 4x^2, where x is a variable representing an unknown value. This expression represents four times the square of the variable x. To simplify this expression, you would multiply 4 by x squared, resulting in 4 times x squared.
The answer to the product of a and b divided by an expression that is 3 times their difference is 3ab(a+b).

Three times the difference of a and m divided by twice their sum is equal to 6(a squared - m squared). 3(a - m)/2(a + m)
The algebraic expression for 5 times a plus 6 times a squared can be written as (5a + 6a^2). In this expression, (5a) represents 5 times the variable (a), and (6a^2) represents 6 times the variable (a) squared.
A cubed

pi times 1/3 times the radius squared times the height
The difference between (5) squared and (7) squared can be calculated by first squaring each number. (5) squared is (25) (since (5 \times 5 = 25)), and (7) squared is (49) (since (7 \times 7 = 49)). The difference between these two results is (49 - 25 = 24). Thus, the difference between (5) squared and (7) squared is (24).
That verbal expression would read: 3(x+y)^2 + 5(2x -y) ^2 means 'squared' in the above example.
The answer to the product of a and b divided by an expression that is 3 times their difference is 3ab(a+b).
The expression "-9 squared" means to multiply -9 by itself. When you calculate this, you get ((-9) \times (-9) = 81). Therefore, -9 squared equals 81.
The expression "4 times x squared" can be written as 4x^2, where x is a variable representing an unknown value. This expression represents four times the square of the variable x. To simplify this expression, you would multiply 4 by x squared, resulting in 4 times x squared.
You can only get a specific number for an expression if you assign numbers to the variables. As an expression, the existing expression cannot be simplified.
It is "a squared minus eighteen b".
