2x - 2
x2+7
The Base in the Algebraic Expression can be a Number or A Variable. EX. 42 or X2 - 4 and X are the base.
Let the number be x and so the expression is 8x
The algebraic expression for three more than a number is: X + 3
37n
2x + 7
It is 2n + 20.
2x + 5
Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
x2+7
Let the original number be y Therefore the new number is given by the expression 2y + 6
Double mean to multiply.For example: the algebra expression 2x can be written in the English Phrases like-Double a Number-Twice a number-Two of a number-Two times a number-or the product of two and a number.
classifacation of algebraic expression according to the number of terms
a common factor
Suppose the function is "multiply a number x by two then subtract three and divide the whole thing by five". The algebraic expression would be: f(x) = (2x-3)/5
2n
The Base in the Algebraic Expression can be a Number or A Variable. EX. 42 or X2 - 4 and X are the base.
