Mathematics
1 answer:
torisob [31]4 years ago
5 0

Answer:

x =  - 4\: or \: x =  9

Step-by-step explanation:

make one side equal to zero:

{x}^{2}  - 5x - 36 = 0

find two factors that multiply to -36 and add to -5 (-9 & 4)

{x }^{2}  - 9x + 4x - 36 = 0

factorise

x(x - 9) + 4(x - 9) = 0

(x + 4)(x - 9) = 0

solve for x

x =  - 4 \: or \: x = 9

How to find median with even amount of numbers?
Paladinen [302]
Sort the numbers in ascending or descending order, then eliminate the greatest and least numbers until you're left with the middle two. The median is the average of the last two numbers.

For example, the median for the set \{2,10,-1,4\}=\{-1,2,4,10\} is 3 because the middle two numbers are 2 and 4, and their average is \dfrac{2+4}2=3.
