Write and simplify the polynomial represented by the model. 1 hundreds block, 5 tens block, 4 ones block A. –x^3 + 2x^2 – 3x + 2 B. x^2 + x – 2 C. –x^2 – x + 2 D. –x^2 + x – 2
What do you mean by blocks?
blocks for the problem
by simplify, does it mean put in this form: (x-3)(x-3)
i half to simplify the polynomial represented by the blocks. my answer choices are a,b,c,d
I actually cannot think of any way to relate those blocks to polynomials. You got anything?
no that why i am asking for help
Maybe the hundred blocks represent values with a power of 3 or 2, the tens block represent values with an exponent of 2 or 1, and ones blocks represent values with an exponent of 1 or no variables.
Or, if I sound completely stupid or like gibberish, http://www.crewtonramoneshouseofmath.com/factoring-polynomials.html
its bit of a read, so try to skim to the important parts. Sorry that I don't have any quicker solutions.
