Solve 2x2 + 12x - 14 = 0 by completing the square
vovangra [49]

Answer:

<h2>x = -7 or x = 1</h2>

Step-by-step explanation:

(a+b)^2=a^2+2ab+b^2\qquad(*)\\\\\\2x^2+12x-14=0\qquad\text{divide both sides by 2}\\\\x^2+6x-7=0\qquad\text{add 7 to both sides}\\\\x^2+2(x)(3)=7\qquad\text{add}\ 3^2=9\ \text{to both sides}\\\\\underbrace{x^2+2(x)(3)+3^2}_{(*)}=7+9\\\\(x+3)^2=16\Rightarrow x+3=\pm\sqrt{16}\\\\x+3=-4\ or\ x+3=4\qquad\text{subtract 3 from both sides}\\\\x=-7\ or\ x=1

What is the answer for 9-0-5-(-20)+(-13)?
Nitella [24]

The correct answer is: 11

Here’s how you solve it!

You can remove the 0 since when you add or subtract 0 it stays the same.

Then you would want to look at the first set of parentheses (-20)

Since it is -(-20) this changes the sign to a positive +20

9-5+20+(-13)

Now since the + is in front of the (-13) it remains the same.

Now you are left with this:

9-5+20-13

9-5=4

4+20=24

24-13=11

Then you are left with your answer: 11

Hope this helps! :3
