Answer:
x=1
Step-by-step explanation:
Since the number ranges between 3 and 10, an equation can't be made because the number is always unknown or can be different every time
Answer: last one.
Step-by-step explanation:
If you would like to calculate (3 * x + 2)^2 - (2 * x - 1)^2, you can do this using the following steps:
(3 * x + 2)^2 - (2 * x - 1)^2 =
9 * x^2 + 12 * x + 4 - (4 * x^2 - 4 * x + 1) =
9 * x^2 + 12 * x + 4 - 4 * x^2 + 4 * x - 1 =
5 * x^2 + 16 * x + 3
The result is 5 * x^2 + 16 * x + 3.
Answer:
so x=-1/2 and 3/2
Step-by-step explanation:
4x²=4x+3
4x²-4x-3=0
by sum and product rule
4x²-6x+2x-3=0
taking common
2x(2x-3)+1(2x-3)=0
(2x+1)(2x-3)=0
either
2x+1=0 or 2x-3=0
2x=-1 or 2x=3
x=-1/2 or x=3/2
solution set={-1/2,3/2}
i hope this will help you :)
