In step two. If we look on the left side of the equation in the first step, it reads 4(2x-4). When a number is multiplying an expression in brackets, we have to multiply every term in the brackets by the number in front of the brackets. In this case, it would be 4*2x + 4*(-4), which is 8x - 16. So the correct option would be the second (8x-16=16+2x) (the right side of the eqtn was 8+2x+8 and if we combine like terms we get 16+2x)
Answer:
Step-by-step explanation:
x^2 + 6x - 2x - 3
x^2 + 4x - 3
answer is C
Answer:
If your looking for I the answer is -3
Step-by-step explanation:
Simplify both sides of the equation
1/2(4i+8)=-2 - Distribute
(1/2) (4i) + (1/2) (8) = -2
The subtract 4 from both sides
Then divide both sides by 2
Answer:
Sum of the solutions of 
is -9.
Product of the solutions of 
is 
Step-by-step explanation:
1.
Given:
The expression whose sum of the solution is required is given as:
For a quadratic equation of the form 
the sum of the solutions is given as:
Sum = 
Here, 
Therefore, the sum of the solutions = 
2.
Rewriting the above equation in a standard quadratic equation, we get:
For a quadratic equation of the form the product of the solutions is given as:
Product = 
Here, 
Therefore, the product of the solutions =
