1.	2. What must be taken away from the product (x – 3)(x2 + 4x – 1) to get 2x3 + x - 3?22
Answer» $\underline{\textsf{Given:}}$ $\mathsf{(x-3)(x^2+4x-1)}$ $\underline{\textsf{To find:}}$ $\textsf{The polynomial <klux>MUST</klux> be taken away from}\;\mathsf{(x-3)(x^2+4x-1)\;to\;get\;2x^3+x-3}$ $\underline{\textsf{Solution:}}$ $\mathsf{Consider,}$ $\mathsf{(x-3)(x^2+4x-1)}$ $\mathsf{=x^3+4x^2-x-3x^2-12x+3}$ $\mathsf{=x^3+x^2-13x+3}$ $\textsf{This can be written as}$ $\mathsf{=(2x^3+x-3)-(x^3-x^2+14x+6)}$ $\therefore\mathsf{x^3-x^2+14x+6\;must\be\;taken\;from\;the\;product\;to\;get\;2x^3+x-3}$ $\underrline{\textsf{Find more:}}$ What must be added to y cube minus y SQUARED minus 3 Y - 22 get a square minus 5 Y + 6 brainly.in/question/16186376
