Solve the quadratic equation by completing the square. x^2+14x+47=0. What is the form and solution?
Phoenix [80]
To complete a square for ax²+bx+c, you first make a=1.
in this case, a is already 1
move c to the right side: x²+14x=-47
next, add (1/2 of b)² to both sides, in this case, b=14, half of 14 is 7, so x²+14x+ 7²=-47+7²
the left side is now a perfect square: (x+7)²=2
x+7=√2 or x+7=-√2
x=√2-7, or x=-2-√7

Please help me I need this answer and I can not figure it out im not smart so could you please help
Rom4ik [11]

So really all you have to do is simply the expressions on top to match them.

Starting with (4t-8/5)-(3-4/3t), distribute the negative sign to the right portion in parentheses, then distribute it all out and you will get 16/3t- 23/5

Basically, use distribution to simplify, here's all the matches:

(4t-8/5)-(3-4/3t) --> 16/3t- 23/5

5(2t+1)+(-7t+28) --> 3t+33

(-9/2t+3)+(7/4t+33) --> -11/4t+36

3(3t-4)-(2t+10) --> 7t-22
