The square root of 144 is 12 (12*12) the square root of 256 is 16 (16*16)
To factor (x² +10x+24); you first have to ask yourself, what 2 numbers will multiply and give me positive 24, but add and give me positive 10? After listing your factors, (1,24)(2,12)(3,8)and (4,6); you decide that (4*6)=24 & adds to get you 10. Meaning that (x²+10x+24) factors are (x+4)(x+6).
Now algebraically, there wouldn't be any other possible value of b, 6, because if you put (-6) & (4), those numbers will multiply and give you (-24) and add & give you (-2); & that is not what you're looking for.
I hope I explained this enough for you to understand. (:
Yes because a propprtion is 2 numbers under each other like 12 is under 8 like a fraction form.
