Question

If (x+4) is a fuctor of x square + m x + 24,
then find the value of m​

Answer 1

Answer:

Given x+4 is a factor so x = - 4 will be the zero

Substituting x value in the given equation

x²+mx+24

(-4)²+m(-4)+24

16 - 4m + 24

-4m +40

-4m = - 40

Therefore m = 10

Answer 2

Answer:

x2+mx+24

we have 24 I. e y×4=24 ie y=6

we know that in term if x we have addition of factor and 24 is multiple of 4 that will be 6

so 4+6=10 which is the valve of m
