4x+6=8x-10
Subtract 4x from both sides
6=4x-10
Add 10 to both sides
16=4x
Divide 4 on both sides
Final Answer: 4=x
Answer:
x³-2x²-22x-21
Step-by-step explanation:
(x+3) (x²-5x-7)
x³-5x²-7x+3x²-15x-21
x³-2x²-22x-21
If there are two values places next to each other (E.g. xy), then the values are multiplied together. In this example, "3n - 2m" is one value as it is in the brackets. The second value is "2".
To simplify, you must open up the brackets. So multiply what is inside the brackets by what is outside. (2 x 3n) - (2 x 2m) = 6n - 4m
