X Squared - Cuemath
x squared is a notation that is used to represent the expression \(x\times x\). i.e., x squared equals x multiplied by itself. In algebra, \(x\) multiplied by \(x\) can be written as \(x\times x\) (or) \(x\cdot x\) (or) \(x\, x\) (or) \(x(x)\)
Square (algebra) - Wikipedia
In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 3 2, which is the number 9.

Equation of a Straight Line - Math is Fun
... choose any value for x and find the matching value for y. For example, when x is 1: y = 2×1 + 1 = 3. So when x=1 we have y=3. Check for yourself that x=1 and y=3 is actually on the line. Or we could choose another value for x, such as 7: y = 2×7 + 1 = 15. So when x=7 we have y=15. Positive or Negative Slope?
