Is 4x a perfect square expression?

A perfect square is a quadratic expression that factors into two identical binomials. Therefore, the quadratic expression x2 + 4x + 4 is a perfect square since it factors into two identical binomials which are (x+ 2) and (x+ 2).

Is 4×2 a perfect square?

Is the first term a perfect square? Yes, 4×2 = (2x) 2 .

Is x2 4x 16 a perfect square trinomial?

What must be added to x2 4x+?

Is X² 18x 81 a perfect square trinomial?

x2−18x+81 is a perfect square trinomial.

Is 16 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.

How do you tell if a trinomial is a perfect square?

A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself. (This is the part where you are moving the other way). In a perfect square trinomial, two of your terms will be perfect squares.

Is x2 81 a perfect square?

Rewrite 81 as 92 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=x and b=9 .

What type of polynomial is x² 18x 81?

complete square
Hence x2+18x+81 is a complete square.

Why is 49 a perfect square?

The square root of 49 is obtained by the number whose square gives the original number. The answer obtained on squaring 7 is 49. Hence, 49 is a perfect square.

What is x2 81?

What is the factor of A² 81?

Rewrite 81 as 92 . Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) a 2 – b 2 = ( a + b ) ( a – b ) where a=a and b=9 .

What are all real square roots of 81?

Explanation: 81=9⋅9 then the square root of √81=9 . Because the double multiplication for the same sign is always positive, the square root is also valid with the other sign 81=(−9)⋅(−9) then √81=−9 and we can say that √81=±9 . What if we do not know the value?
