An expression has numbers, variables, and mathematical operations. The factors of the expression 4x³+x²-8x-2 by grouping are x²(4x+1)-2(4x+1).
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The factors of the expression by grouping can be done as,
[tex]4x^3+x^2-8x-2[/tex]
Take x² as the common factor from the first two terms while -2 from the last two terms,
[tex]4x^3+x^2-8x-2\\\\=x^2(4x+1)-2(4x+1)[/tex]
Thus, the factors of the expression 4x³+x²-8x-2 by grouping are x²(4x+1)-2(4x+1).
