Answer: x=−1/2,4/3
Step-by-step explanation:
1. Split the second term in 6x^2−5x−4 into two terms.
6x^2+3x−8x−4=0
2. Factor out common terms in the first two terms, then in the last two terms.
3x(2x+1)−4(2x+1)=0
3. Factor out the common term 2x+1.
(2x+1)(3x−4)=0
4. Solve for x.
Ask: When will (2x+1)(3x−4) equal zero?
When 2x+1=0 or 3x-4=0
Solve each of the 2 equations above.
x=−1/2,4/3
Step-by-step explanation:
Given the average of 8 numbers = 56.
Then the Total sum of 8 numbers = 56 * 8
= 448.
Sum of 1st three numbers = 49 + 57 + 72
= 178.
So, the total = 448 - 178
= 270.
Average of the other 5 numbers = 270/5
= 54.
Verification:
178 + 270 = 448/8
= 56.
