Answer:
[tex]6x^{2}[/tex]-12x-90
Step-by-step explanation:
2x*3x=6x^2
2x*9=18x
3x*-10=-30x
18x-30x=-12x
-10*9=-90
The expression when the provided equation (2x-10)(3x+9) is Express as a trinomial is 3x²-12x-90.
What is trinomial?
Trinomial is the polynomial equations which consist of three terms (non-zero) and two or more than two variables.
The given expression in the problem is,
[tex](2x-10)(3x+9)[/tex]
Let the trinomial of this expression is f(x). Solve, it and open the bracket as,
[tex]f(x)=(2x-10)(3x+9)\\f(x)=(2x\times3x+2x\times9)-(10\times3x+10\times9)\\f(x)=(6x^2+18x)-(30x+90)\\f(x)=6x^2+18x-30x-90\\f(x)=6x^2-12x-90[/tex]
Thus, the expression when the provided equation (2x-10)(3x+9) is Express as a trinomial is 3x²-12x-90.
