Question

Question 1.1. What is the first step in solving x2 + 2x + 3 = 0 by completing the square?
(Points : 1)
Factor the left side.

Add 1 to each side of the equation.

Divide both sides of the equation by 2.

Subtract 3 from each side of the equation.

Answer 1

add 2x to x which equeals 3 times 2 (multiplied by) = 6+3= 9-0= -9

Answer 2

the first step to solving an equaiton of the form\[ax^2+bx+c=0\]by completing the square is by first dividing by a, giving\[x^2+\frac bax+\frac ca=0\]then adding \(\large\left(\frac b{2a}\right)^2\) to both sides.
Which of your choices does that correspond to?

Answer 3

A.)?

Answer 4

@TuringTest

Answer 5

what do you think @ZachH54

Answer 6

I'm pretty sure you have to ad the x together to reach your answer.

Answer 7

So A, B, C, or D?

Answer 8

I now say C

Answer 9

C

Answer 10

what was the first step I said, technically?
divide by \(a\), and what is \(a\) in this case?

Answer 11

the answer is not C, by the way

Answer 12

I would say isolate all terms in x from any constants....

Answer 13

so manage the constant 1st
