Question

Divide 3x(5x2 + 10x3 + 5) - (x2 - 4 - 2x) by (- 3+5x) by chapter polynomials​

Answer 1

$\text{First do it in stardard form :-}$

$\sf= 3x(5x²+ 10x³ + 5) - (x²- 4 - 2x)$

$\sf \: = 15x³+30x⁴+15x-x²+4+2x$

$\sf \: = 15x³+30x⁴+15x+2x -x²+4$

$\green{ \sf \: = 15x³+30x⁴+17x-x²+4}$

Standard form = 30x⁴+15x³-x²+17x+4

30x⁴+15x³-x²+17x+4 by (5x-3)

use long division method and solve :-
