Answer:
a=2
b=0
c=12
Step-by-step explanation:
The standard form of a quadratic equation is ax²+bx+c=0
Here's the given equation:
2x²+12=0
You might notice that the term bx is not there (there is just ax² and c). That means that b is 0.
The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2
12 has no variable, so that means it'll be c in the equation.
Hope this helps!
Answer:
x = 5
Step-by-step explanation:
1. Expand
8x - 5x + 5 = 20
2. Simplify
3x + 5 = 20
3. Subtract 5 from both sides
3x = 20 - 5
4. Simplify
3x = 15
5. Divide both sides by 3
x = 15/3
6. Simplify
x = 5
