Standard form of a polynomial is ordering all terms from the highest degree (power) to the lowest degree. Which polynomial is in standard form? x13 + 5x - 34 + 2x x13 - 3x7 + 5x6 - 8 x13 + 5x8 + 7x2 - x6 x7 + 5x4 + 7x - x2 + 8 Fill in the missing exponent so that the polynomial will be in standard form. (+) 3x2 + 6x + 2 When Combining Polynomials, ONLY the coefficient (number in front) changes !!! 4x2 + 3x + 5 x2 + x + (+) 4x2 + 4x – 2 When Combining Polynomials, ONLY the coefficient (number in front) changes !!! 5x2 - 2x + 9 x2 + x + (+) 4x2 - 5x +4 5x2 - 3x - 9 x2 x 5 The terms in the POLYNOMIAL SUM must be connected by + or – signs. (-4x3 + 2x - 8) + (8x3 - 8x2 + x + 5) Write the simplified expression in standard form. operation symbols Simplify and write the simplified expression in standard form. (-4x3 + 2x - 8) - (8x3 - 8x2 + x + 5) -4x3 + 2x - 8 8x3 8x2 x 5 First, change the sign of each term in the second expression: operation symbols (3x2 + x + 4) - (8x - x2 + x - 7) Write the simplified expression in standard form. operation symbols |
