What is 2x with the exponent 2 plus 3x plus 1. what is 7n with the exponent 2 plus 9n plus 2. what is 3x with the exponent 2 plus 8x plus 5. what is 7y with the exponent 2 plus 19y plus 10?
The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.
Are there any values of the variable A for which the expressions 2 plus A and 2A have the same value?
2. 2 plus 2 equals 4 and 2(2)= 4
What are 2 equivalent expressions for 5b plus 5b?
5b + 5b = 2 x 5b
What are the solutions to -x squared plus 2x plus 4 and x-2?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
What is the sum of multiplication expressions?
The sum of multiplication expressions is the answer that you'd have, if you added together more than one multiplication expression. For example: 3 x 4 + 5 x 2 = A <--- A = the answer after you do/evaluate the expressions 12 + 10 = A 22 = A 22 is the sum of the above multiplication expressions (i.e. 3 x 4 plus 5 x 2)
Expressions like 4(3 plus 2) and 4(3) plus 4(2)?
Such expressions illustrate the distributive property of multiplication over addition in the field of real numbers.

The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.
Two linear expressions with a sum of -5x plus 4?
Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).
Are there any values of the variable A for which the expressions 2 plus A and 2A have the same value?
2. 2 plus 2 equals 4 and 2(2)= 4
