The polynomial is subtracted using the distributive property.
.. (16k^3 -3v^4) -(-9k^3 +6v^4)
.. = 16k^3 -3v^4 +9k^3 -6v^4
.. = (16 +9)k^3 +(-3 -6)v^4
.. = 25k^3 -9v^4
"Invert" means different things in different contexts. Here we suppose it means you simply want the reciprocal of this difference:
The given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial.
<h3>What is a perfect trinomial?</h3>
A perfect square trinomial is takes the algebraic expression form ax^2 +bx + c, where the square root of the first term and the third term is the equation to the second term.
Given that:
-(3x + 5)^2
Open brackets
= - (9x +30x + 55)
Multiply through by (-)
= -9x^2 - 30x - 55
Therefore, we can conclude that the given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial. i.e. the multiplication of the square root of the first and the third term did not result in the 2nd term.
