Answer:
x= 2.28
or, x= 0.219
Step-by-step explanation:
2x²-5x+1 =0
a= 2, b= -5 and c= 1
x= (-b <u>+</u> √(b²-4ac))/2a
= (5 <u>+</u> √(25-8))/4
= (5 <u>+</u> √17)/4
3t-18t+4=-26
first you want to move the 4 to the other side of the equation so subtract that from both sides of the equation which gives you this 3t-18t=-30.
Next you would combine the like terms that are on the left side of the equation giving you -15t=-30. Now you want t by itself so you divide both sides by -15 which would give you t=2
A represents 12!
12! = 12 * 11 * 10 * 9 * ... (down to 1)

Answer:
x=2
Step-by-step explanation:
implifying
12x + 8 = 32
Reorder the terms:
8 + 12x = 32
Solving
8 + 12x = 32
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 12x = 32 + -8
Combine like terms: 8 + -8 = 0
0 + 12x = 32 + -8
12x = 32 + -8
Combine like terms: 32 + -8 = 24
12x = 24
Divide each side by '12'.
x = 2
Simplifying
x = 2
