Step-by-step explanation:
add 8 to get to 0.
and 9 more to get to point 9.
add 8 and 9 to get the answer of 17.
Its a rate with 1as the second term
Answer:
x = -8, x = 4
Step-by-step explanation:
x² + 4x - 12 = 0
(x + 8) (x - 4) = 0
x + 8 = 0, x = -8
x - 4 = 0, x = 4
<h2>Steps</h2>
So to find the solutions, I will be factoring by grouping. Firstly, what two terms have a product of 12x² and a sum of -8x? That would be -2x and -6x. Replace -8x with -2x - 6x:

Next, factor 4x² - 2x and -6x + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:

Now you can rewrite it as:

Now, apply the zero product property and solve:

<h2>Answer</h2>
<u>In short, x = 3/2 (1.5) and 1/2 (0.5).</u>
17^2 = 289
18^2 = 324
Any of the numbers between 289 and 324 exclusive will have a root between 17 and 18
Eg sr(300) = 17.3205... is between 17 and 18 on the number line.
