Question

Divide 2x³+5x²+8x-3 by x+1

Answer 1

Answer:

q= 2x^2+3x+5

r=(-8)

Step-by-step explanation:

(2x^3+5x^2+8x-3)÷(X+1)

= q-----2x^2+3x+5

r----- ( -8)

Answer 2

Step-by-step explanation:

division by factorisation method

2x³+5x²+8x-3

= 2x³+2x²+3x²+3x+ 5x+5 - 8

= 2x²( x+1) +3x(x+1) +5(x+1) - 8

= (x+1) ( 2x²+3x+5) - 8

= divisor × quotient + remainder

=> quotient = 2x²+3x+5

=> remainder = - 8
