Question

divide the polynomial 3x^4-4x^3-3x-1 by x-1​

Answer 1

Answer:

x value is (3) and Divide the Polynomial is 131

Step-by-step explanation:

x value is: Part 1

${3x}^{4} - {4x}^{3} - 3x - 1 \: \: by \: \: x - 1 \\ \frac{ {3x}^{4} - {4x}^{3} - 3x - 1 }{x - 1} \\ {3x}^{4} - {4x}^{3} - 3 \\ {( - 1x)}^{1 } - 3 \\ ( - 1x) - 3 \\ 1x + 3 \\ x = \frac{3}{1} \\ x = 3$

Divide the Polynomial: Part 2

${3x}^{4} - {4x}^{3 } - 3x - 1 \: \: by \: \: x - 1 \\ \frac{ {3x}^{4} - {4x}^{3} - 3x - 1}{x - 1} \\ \frac{ {3(3)}^{4} - {4(3)}^{3} - 3(3) - 1 }{(3) - 1} \\ \frac{3(81) - 4(27) - 3(3) - 1}{(3) - 1} \\ \frac{243 - 108 - 9 - 1}{2} \\ \frac{135 - 8}{2} \\ 135 - 4 \\ 131 \: \: is \: \: answer$
