Q. The expression x+2x3+2x2+x+6 is equivalent to(1) x2+3(3) 2x2+x+6(2) x2+1+x+24(4) 2x2+1+x+24
Perform Division: Perform polynomial long division or synthetic division to simplify the expression.We will divide the polynomial x3+2x2+x+6 by x+2.
Set Up: Set up the division.Write x3+2x2+x+6 under the division bar and x+2 outside the division bar.
Divide First Term: Divide the first term of the dividend by the first term of the divisor.Divide x3 by x to get x2.Write x2 above the division bar.
Multiply and Subtract: Multiply the divisor by the result from the previous step.Multiply x+2 by x2 to get x3+2x2.Write this result under the corresponding terms of the dividend.
Repeat Division: Subtract the result from the previous step from the dividend.Subtract (x3+2x2) from (x3+2x2) to get 0.Bring down the next term of the dividend, which is x.
Divide Next Term: Repeat the division process with the new dividend.Divide x by x to get 1.Write 1 above the division bar next to x2.
Multiply and Subtract: Multiply the divisor by the result from the previous step.Multiply x+2 by 1 to get x+2.Write this result under the corresponding terms of the new dividend.
Repeat Division: Subtract the result from the previous step from the new dividend. Subtract (x+2) from (x) to get −2. Bring down the next term of the dividend, which is 6.
Add Final Term: Repeat the division process with the new dividend.Divide −2 by x to get 0, since −2 cannot be divided by x to give a polynomial term.Write 0 above the division bar next to 1.
Write Final Result: Add the final term of the dividend to the remainder.The remainder is now −2+6, which simplifies to 4.
Match with Options: Write the final result of the division.The quotient is x2+1, and the remainder is 4.The expression can be written as x2+1+x+24.
Match with Options: Write the final result of the division.The quotient is x2+1, and the remainder is 4.The expression can be written as x2+1+x+24.Match the result with the given options.The equivalent expression is x2+1+x+24, which corresponds to option (2).
