Step-by-step explanation:
Answer:
6x² + 5x - 2 = 0
Step-by-step explanation:
Given
2x² - 5x - 6 = 0 ← in standard form
with a = 2, b = - 5, c = - 6, then
sum of roots α + β = -
= 
product of roots =
= - 3, then
sum of new roots =
+ 
= 
=
= - 
product of new roots =
× 
=
= - 
Hence the required equation is
x² +
x -
= 0 or
6x² + 5x - 2 = 0 ( multiplying through by 6 )
Answer:
0/1 = 0
Step-by-step explanation:
0/1
0 ÷ 1 = 0
Answer:
16 mph
Step-by-step explanation:
Givens:
4 hours total time
48 miles total distance
So our equation should look like this.
48 = 2x(2) + x(2)
Where x = speed second half of trip.
x = 8
x*2 = 16 mph
To solve for E you'll add 867 to 108.
E - 867 = 108
E = 108 + 867
E = 975
Hope this helps :)
