Answer» ONG>Answer: Divisor = x^2+3x+1x2+3x+1 Dividend = 3x^4+5x^3-7x^2+2x+23x4+5x3−7x2+2x+2 Now , Dividend = (Divisor \times Quotient)+RemainderDividend=(Divisor×Quotient)+Remainder 3x^4+5x^3-7x^2+2x+2= (x^2+3x+1 \times 3x^2)+(-4x^3-10x^2+2x+2)3x4+5x3−7x2+2x+2=(x2+3x+1×3x2)+(−4x3−10x2+2x+2) 3x^4+5x^3-7x^2+2x+2= (x^2+3x+1 \times 3x^2-4x)+(2x^2+6x+2)3x4+5x3−7x2+2x+2=(x2+3x+1×3x2−4x)+(2x2+6x+2) 3x^4+5x^3-7x^2+2x+2= (x^2+3x+1 \times 3x^2-4x+2)+(0)3x4+5x3−7x2+2x+2=(x2+3x+1×3x2−4x+2)+(0) Thus remainder is 0 So, x^2+3x+1x2+3x+1 is a factor of 3x^4+5x^3-7x^2+2x+23x4+5x3−7x2+2x+2 Hence x^2+3x+1x2+3x+1 is a factor of 3x^4+5x^3-7x^2+2x+23x4+5x3−7x2+2x+2 Step-by-step explanation: please follow me |
