One of the zeros of quadratic polynomial (k-1) x2 + kx + 1 is -3 then the valu of k is.. ....... guys please give me only right answer ​

Answer»

s zero of POLYNOMIAL so (X+3) gonna be a factorHence let g(x) = 2(K-1) + KX + 1g(-3) = 2(K-1) + K(-3) + 1As g(-3) is factor0 = 2(K-1) - 3K + 10 = 2K-2-3K+10 = -K - 1So K = -1...If you need more HELP in MATHS then you can ask me.....hope it HELPS
