Find the solution set of the quadratic equation over the set of complex numbers.
blagie [28]
Step 1: Multiply 5x2 = 10 so the equation after the first step should look like this 10 + 12x + 8 = 0.

Step 2: Subtract 10 from the 8 and the number by itself cause whatever you do to one side you must do to the other. so the equation should look like this after the second step 12x + -2 = 0 because we subtracted the 10 and the 8.

Step 3: Now we must add the 2 to both sides because we have to do the inverse operation in this problem so once we've done this it should end up looking like this after the 3rd step 12x = 2 because the 2 was a negative.

Step 4: the final step we must divide since an anytime we have a number next to a variable it means multiply but since were using order of operations we have to do the opposite/inverse operation in this problem and we would divide 12 by 2 and get our final answer as x = -6 because the 12 would cancel itself out leaving us with 2 divided by 12 which is 0.16 or -6 depending on if you want it simplified or not the simplified answer would be 0.16 and the non simplified version would be -6

Write the equation of the line that passes through the points (2, 1) and (5, -8)
My name is Ann [436]

Answer:

The answer is y = -3x + 7.

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

y = mx + b

❃Incase you also forgot, what the slope formula is ☟

m =  \frac{y_2 - y_1}{x_2 - x_1}

➊ First: We are going to be solving for the slope.

m =  \frac{ - 8 - 1}{5 - 2}  =  \frac{ - 9}{ \:  \:  \: 3}  =  - 3

➋Second: We find the y-intercept.

y = mx + b \\ 1 = - 3(2) + b \\ 1 = - 6 + b \\ \frac{ + 6 = + 6 \: \: \: \: \:  \:  \:  \:  \: }{7 = b}

➌Third: Plug in.

y =  - 3x + 7
