Answer:
2b²(8b²+15b-6)
Step-by-step explanation:
16+30b³-12b²
2b²(8b²+15b-6)
This is not further factorable. If you want to find the roots, you'd have to use the quadratic formula for the polynomial in the parentheses. Therefore that is our final answer.
Answer:
A.) After adding 4 to both sides, the equation is
C.) The equation can be solved for x using exactly one more step by multiplying both sides by
D.) The equation can be solved for x using exactly one more step by dividing both sides by
Step-by-step explanation:
The correct questions is as follows:
Carina begins to solve the equation -4-2/3x=-6 by adding 4 to both sides. Which statements regarding the rest of the solving process could be true? Check all that apply.
A.) After adding 4 to both sides, the equation is -2/3x=-2.
B.) After adding 4 to both sides, the equation is -2/3x=-10 .
C.) The equation can be solved for x using exactly one more step by multiplying both sides by -3/2.
D.) The equation can be solved for x using exactly one more step by dividing both sides by -2/3.
E.) The equation can be solved for x using exactly one more step by multiplying both sides by -2/3.
Given equation:
To show the steps we will carry out in order to solve for
Solution:
Solving for
Step 1:
Adding both sides by 4
Thus, we get:
Thus statement A is correct.
Step 2:
Multiplying both sides by
Thus, we get:
[Two negatives multiply to give a positive]
This proves that statement C is correct.
Or Step 2:
Dividing both sides by
Thus, we get:
[On dividing with a fractional divisor, we take reciprocal and multiply it with the dividend.]
[Two negatives multiply to give a positive]
This prove that statement D is correct.
