We evaluate b^2 - 4ac. If the answer is positive, then there are two real solutions. If it is zero, there is one real solution. If it is negative, there are 2 complex solutions. In this equation, a = 1, b = 5, c = 7. Now we plug in the numbers.
Because this answer is positive, there are two real solutions.
Answer: 9.3d−g-10.4f
Step-by-step explanation:
1) -512, 1024, -2048. You just multiply by -2.
2)7.8125, -3.9062, 1.9531. You divide by -2

Answer:</h2>
First, we need to use <u><em>slope formula*</em></u> to find the slope.
Second, we use the slope we found and <em>ONE</em> of the 2 points listed and plug it into <u><em>slope-intercept form**</em></u> to solve for <u><em>b</em></u>.
Here is what we have so far:
I'm going to use this point:
Here is how to find <em>b</em>:
Finally, we put all of it together and we have our equation.
*Slope formula: <em>m = y₂ - y₁/x₂ - x₁</em>
**Slope-intercept form: <em>y = mx + b</em>
