Answer:
(B , D) = (-2,5)
Step-by-step explanation:
The given quadratic expression is
![3x^{2} -x-10](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20-x-10)
compare the given expression with ![ax^{2} +bx+c](https://tex.z-dn.net/?f=ax%5E%7B2%7D%20%2Bbx%2Bc)
so we have ![a = 3 , b = -1 ,c = -10](https://tex.z-dn.net/?f=a%20%3D%203%20%2C%20b%20%3D%20-1%20%2Cc%20%3D%20-10)
now
and ![b= -1](https://tex.z-dn.net/?f=b%3D%20-1)
we need to find two numbers such that their product is -30 and sum is -1
-6 and 5 are such numbers
so we have
![3x^{2} -6x+5x-10](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20-6x%2B5x-10)
grouping first two terms and last two terms
![(3x^{2} -6x)+(5x-10)](https://tex.z-dn.net/?f=%283x%5E%7B2%7D%20-6x%29%2B%285x-10%29)
factor out 3x from first two terms and 5 from last two terms
( factor out (x-2))
![(x+(-2))(3x+5)](https://tex.z-dn.net/?f=%28x%2B%28-2%29%29%283x%2B5%29)
hence B =-2 and D= 5
(B,D)= (-2,5)
Because if you rotate an object 360 degrees it’s like the object never moved because the object would still be in the same spot as if you didn’t move it
