If x=-2 is a root of the equation 3×2+7x+p=0 ,find the values of k,so that the roots of the equation x2+k[4x+k-1[+ p=0 are equal – 1770252 Arielpops Arielpops 14.11.2017 Math Secondary School, If x = – 2 is a root of the equation 3×2 + 7x + p = 0 , find the value of k so that the roots of the equation x2 + k(4x + k -1) + p = 0 are equal.
Quadratic Equations if x = -2 is a root of equation 3×2 + 7x + p=0 , find the values of k so that the roots of equation x2+k(4x+k-1)+ p=0 are equal. Share with your friends, Since ?2 is a root of the equation 3x 2 + 7x + p = 0 , 3(?2) 2 + 7(?2) + p = 0 ? 12 ? 14 + p = 0 ? p = 2 ? The equation becomes 3x 2 + 7x + 2 = 0. Putting p = 2 in x 2 + k(4x + k ? 1) + p = 0 , we get x 2 + k(4x + k ? 1) + 2 = 0 x 2 + 4kx + (k 2 ? k + 2) = 0. This equation will have equal roots, if the discriminant is zero.
