Sum and products of zeroes of quadratic polynomial are -1/4 & 1/2 respectively. Find the polynomial. |

Answer» Sum= -1/4 product= 1/2 use formula make quadratic polynomial formula is x² - (sum of zeroes)x +(product of zeroes) putting the value x²- (-1/4)x + (1/2) ans ayega x² + 1/4+1/2. Fir hum multiply krege 4 se jisse divide ki value chali jaye like 4x²+ 4× 1/4 + 4×1/2 to humare pss equation ayegi 4x²+ x +2 ye humara quadratic polynomial banega (a+b)=-1/4(ab)=1/2Putting the value of (a+b),(ab).P(x)=x2+( a +b)x-(ab) x2-1/4x-1/24x2-1x-2hence the polynomial is 4x2-1x-2 |
