SOLUTION: factoring completely 16x^2 + 24x + 9. 16*9=144 the 2 factors of 144 whose sum is 24 are 12 & 12. =4x(4x+3)+3(4x+3) factor by grouping.
Is 16×2 − 24x − 9 a perfect square trinomial?
Yes, it is.
Is 16x 9 a perfect square?
In addition to factoring 16x^2+9, we will also verify that our answer is correct by calculating the product of the factors we found. Before we begin, note that 16 and 9 are both perfect squares.
What is the factor of 16x 2 25?
The answer is: (4x−5)(4x+5) . This polynomial is a difference of squares, and there is this formula to factor: a2−b2=(a−b)(a+b) .
Can a polynomial be factored into a rational function?
Polynomials with rational coefficients always have as many roots, in the complex plane, as their degree; however, these roots are often not rational numbers. In such cases, the polynomial will not factor into linear polynomials. Rational functions are quotients of polynomials.
Which is the best tool for factoring polynomials?
Wolfram|Alpha is a great tool for factoring, expanding or simplifying polynomials. It also multiplies, divides and finds the greatest common divisors of pairs of polynomials; determines values of polynomial roots; plots polynomials; finds partial fraction decompositions; and more.

When do you use factoring to find rational roots?
In such cases, the polynomial is said to “factor over the rationals.” Factoring is a useful way to find rational roots (which correspond to linear factors) and simple roots involving square roots of integers (which correspond to quadratic factors).
