Question

Multiple i) (5x²+4x-2) by (3-x-4x²)​

Answer 1

Answer:

Step-by-step explanation:

$(5x^{2} +4x-2)$×$(3x-x-4x^{2} )$

$[5x^2$×$(3x-x-4x^2)]$$+[4x$×$(3x-x-4x^2)]$$-[2$×$(3x-x-4x^2)]$

$[15x^3$$-5x^3-20x^4]$+$[12x^2-4x^2-16x^3]$-$[6x-2x-8x^2]$

$(10x^3-20x^4)+(8x^2-16x^3)-(4x-8x^2)\\10x^3-20x^4+8x^2-16x^3-4x+8x^2\\-20x^4-16x^3+10x^3+8x^2+8x^2-4x\\-20x^4-6x^3+16x-4x$
