Solve the following quadratic equations by completing the square.<br><br> y^2-14y+48=0
NISA [10]

Answer:

  y = 6 or 8

Step-by-step explanation:

1. Subtract the constant:

  y^2 -14y = -48

2. Add the square of half the y-coefficient:

  y^2 -14y +49 = -48 +49

Write as a square, if you like:

  (y -7)^2 = 1

3. Take the square root:

  y -7 = ±√1 = ±1

4. Add the opposite of the constant on the left:

  y = 7 ±1  =  6 or 8

The solution is y = 6 or y = 8.

brilliants [131]

Answer:

Final answer is 2y^4 \sqrt{5}.

Step-by-step explanation:

Given expression is \sqrt{20y^8}.

Now we need to smplify the given expression \sqrt{20y^8}.

So begin with factoring 20 into two parts so that one part is perfect square number.

\sqrt{20y^8}

=\sqrt{4 \times 5y^8}

=\sqrt{4 y^8} \times \sqrt{5}

=2y^4 \times \sqrt{5}

Hence final answer is 2y^4 \sqrt{5}.
