N=-6
-6 minus 6 is -12
-12 /3 is -4 since the negative doesn’t cancel out
Answer:
12/20
Step-by-step explanation:
This means that we will plug 3 into our x values.
Our rule is 5x.
This means that:
5(3)
This means our final answer will be 15.
Answer:
-2.61803398875, -0.38196601125
or
(-3±√5)/2
Step-by-step explanation:
First, expand. (2x+3)² = 4x²+12x+9=5
4x²+12x+4 = 0
Quadratic equations take the form ax²+bx+c = 0
In this case,
a = 4
b = 12
c = 4
You can solve with the equation x=(-b±√b²-4ac)/2a
Plug in:
(-12±√144-64)/8
(-12±√80)/8
(-12±√2^4×5)/8
(-12±4√5)/8
(-3±√5)/2
Final answer x = (-3±√5)/2
If you want decimal form: -2.61803398875, -0.38196601125
