Answer 1

in cubic polynomial factorisation is done by assuming the factor of given polynomial which makes it 0.

Answer 2

Answer:

(x+1)(2x+3)(2x-1)

Step-by-step explanation:

4x³+8x²+x-3

=4x³+4x²+4x²+x-3

=4x²(x+1) +4x²+4x-3x-3

=4x²(x+1) +4x(x+1)-3x(x+1)

=(x+1)(4x²+4x-3)

=(x+1)(4x²+6x-2x-3)

=(x+1) ( 2x(2x+3)-(2x+3) )

=(x+1)(2x+3)(2x-1)
