Equation, not expression. A and B are two numbers.
(A + B)2 = A2 + B2 + 2(AB)

Sum of squares? Product?
81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.
By definition, ALL perfect squares are whole numbers!
36 details: the numbers are 1,2,3 the squares 1, 4, 9 the produc 1 x 4 x 9 = 36
No. Perfect squares as the squares of the integers, whereas irrational squares as the squares of irrational numbers, but some irrational numbers squared are whole numbers, eg √2 (an irrational number) squared is a whole number.
Sum of squares? Product?
what is the process of writing a expression as a product? is it Factoring, Quadractic equation, perfect Square trinomial or difference of two squares

The numbers are 21 and 24. 576 - 441 = 135
The only squares I can think of related to life is "three squares", as in the expression, "All I need are 3 squares and a bed." That expression means, "All I need are three nutritious meals and a place to sleep."
Look for odd squares. Multiplying odd numbers results in an odd product.
4x2 - 36 = (2x-6)(2x+6) A very useful general rule is this : - When an algebraic expression is the difference of two squares e.g. a2 - b2 then it factorises into (a - b) (a + b).
With square roots if you have a number times itself or squared then that that product is that numbers square root example: 9x9= 81 81 square root is 9
That expression can't actually be factored without using complex numbers. If you want to use complex numbers, then it would come out as a "difference of squares":(x + i)(x - i)

In the complex field, every number is a square so there are no numbers that are not squares. If the domain is reduced to that of real numbers, any negative number is not a square. However, the term "square numbers" (not number's!) is often used to refer to perfect square numbers. These are numbers that are squares of integers. Therefore the squares of fractions or Irrational Numbers are non-squares.
