Zeroes of quadratic polynomial and verify relationship between zeroes and coefficients 4u²+8u |
|
Answer» Here, 4u^2+8u=0 =4u(u+2)=0 4u=0 or u+2=0 U=0 or u=-2 :. Zeroes of the given quadratic equation is 0 and -2 Then, alpha=0 and beta=-2 Where, a=4, b=8, c=0 The relationship between zeroes and coefficient of given quadratic equation: Alpha+beta=-b/a :.0+(-2)=-8/4 -2=-2 Alpha×beta=c/a :.0×-2=0/4 0=0 Here, 4u^2+8u=0=4u(u+2)=04u=0 or u+2=0U=0 or u=-2:. Zeroes of the given quadratic equation is 0 and -2Then, alpha=0 and beta=-2Where, a=4, b=8, c=0The relationship between zeroes and coefficient of given quadratic equation:Alpha+beta=-b/a:.0+(-2)=-8/4-2=-2Alpha×beta=c/a:.0×-2=0/40=0 |
