Question

ONE ZERO OF POLYNOMIAL X2+11X+K IS -3 FINSK AND OTHER ZERO

Answer 1

x^2+11x+k is the polynomial

one zero = -3

so, x^2+11x +k =0
=> (-3)^2+(11×-3)+k=0
=> 9-33+k =0
=> k=24

now, x^2+11x+24=0
=>x^2+8x+3x+24=0
=>x(x+8)+3(x+8)=0
=>(x+3)(x+8)=0

hence, x= -3 and -8
so , other zero is -8 answer
