Answer:
m= -10,-5
Step-by-step explanation:
Given : Equation x^2+mx-24=0x2+mx−24=0
To find : Two values of m
Solution : We use middle term split formula
→Form = ax^2+bx+c=0ax2+bx+c=0 in which we split the middle term such that sum of their term is b and product of term is (a×c).
So, we factor the -24
24 = -12×2
24= -8 × 3
or many more but we just need two.
Therefore, we use these factors
(x+12)(x-2)=0 By null factor law, x=-12, 2, which are integer roots
Now the middle term b is addition of the factors
so,-12+2 =10
Therefore, x^2-10x-24=0x2−10x−24=0 , thus m=-10
(x+8)(x-3)=0 By null factor law, x=-8,3, which are integer roots too
Now the middle term b is addition of the factors
so,-8+3 =-5
Therefore, x^2-5x-24=0x2−5x−24=0 , thus m=-5
There can be other combinations too, which is evident based on the nature of factorization, which gives other possible m values.
Therefore, m= -10,-5
m= -10,-5
