Question

Fill in the blanks6. if the equations x +7x+12 = 0 and xe+mx+5 = 0 have common roots the value of m is equal toO has reroots​

Answer 1

Step-by-step explanation:

x^2+7x+12=0............(a)

(x+4) (x+3)=0

x= -4, -3

x^2+mx+5=0............... (b)

sub x values in (b)

x= -4

(-4)^2+m(-4)+5=0

m =21/4

x=-3

(-3)^2+m(-3)+5=0

m = 14/3

m= 21/4, 14/3
