Is 1 a perfect square?

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

Are roots and zeros the same?

A root or a zero of a polynomial are the value(s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, and zero is the Y-value. It is not saying that imaginary roots = 0.

How do you solve roots?


  1. Square a number by multiplying it by itself.
  2. For square roots, find the “reverse” of a square.
  3. Know the difference between perfect and imperfect squares.
  4. Memorize the first 10-12 perfect squares.
  5. Simplify square roots by removing perfect squares when possible.

What is the perfect square trinomial formula?

An expression obtained from the square of a binomial equation is a perfect square trinomial. An expression is said to a perfect square trinomial if it takes the form ax2 + bx + c and satisfies the condition b2 = 4ac. The perfect square formula takes the following forms: (ax)2 + 2abx + b2 = (ax + b)

How do you factor perfect squares?

Factoring perfect square trinomials: ( a + b ) 2 = a 2 + 2 a b + b 2 (a + b)^2 = a^2 + 2ab + b^2 (a+b)2=a2+2ab+b2 or ( a − b ) 2 = a 2 − 2 a b + b 2 (a – b)^2 = a^2 – 2ab + b^2 (a−b)2=a2−2ab+b2 – Factoring Polynomials.
