X^2-2x=-205 find the x value |
|
Answer» st term is, X2 its coefficient is 1 .The middle term is, +2x its coefficient is 2 .The last term, "the constant", is -205 Step-1 : Multiply the coefficient of the first term by the constant 1 • -205 = -205 Step-2 : Find TWO factors of -205 whose sum equals the coefficient of the middle term, which is 2 . -205 + 1 = -204 -41 + 5 = -36 -5 + 41 = 36 -1 + 205 = 204 Observation : No two such factors can be found !! |
