This principle is crucial in coordinate geometry, where distances are always positive values, and in solving quadratic equations where variables might represent negative quantities. For example, the square of a variable "x" is written as x², which represents x multiplied by x.
Check Squares Using Square Root Trick
To find the square of 7, you would calculate 7 times 7. Instead of writing "8 times 8," you write 8².
Using the formula for squaring a binomial (a + b)² = a² + 2ab + b², you calculate 100 + 40 + 4, which sums to 144. This notation is particularly useful when dealing with algebraic expressions.

To square a number means to multiply that number by itself, denoted by a small superscript 2 or the word "squared" following the value. Similarly, the formula for calculating kinetic energy (1/2 mv²) relies on the square of the velocity (v) to determine the energy of a moving object.
