If I'm right, 14/3 m and 2/3 m are like terms, so -14/3m+2/3m= -12m. Your answer is then 12-12m
Answer:
c= 9
Step-by-step explanation:
first you would need to get the variable alone
next you would take the one and since it is subtraction you would do the opposite addition
then you would add one to each side and the two ones cancel each other out so the you add 8 and 1 and get nine so c would equal 9

Answer:
The value of k is
The roots are -1 and
Step-by-step explanation:
In any quadratic equation the sum of its roots is and the product of its root is
In the equation
The sum is
The product is
∵ The sum of the roots is twice their product
∴
∴ ⇒Multiply both sides by k
1 + k = 6k + 4⇒ 1 - 4 = 6k - k
5k = -3 ⇒
Use the value of k in the equation:
⇒ Multiply equation by 5
⇒ Multiply equation by -1
⇒ use factorization to find roots
(3x - 1)(x + 1) = 0
3x -1 = 0⇒ 3x = 1⇒ x = 1/3
x + 1 = 0⇒ x = -1
The roots are 1/3 and -1
