Use perfect square factoring patterns<br> y^2 + 16y + 64 = 0

Pepsi [2]

Arrange your given equation to resembles the form
a^2 +2ab+ b^2 because this equals (a+b)^2

So we get:
y^2+16y+8^2=0

Now compare
y^2+16y+8^2 to a^2 +2ab+ b^2

So we got
y^2+2•8 y+8^2=0 which equals (y+8)^2

ohaa [14]

For this case we must find the value of the following expression:

$4a ^ 2b-c$

When:

$a = 5\\b = 4\\c = 6$

Substituting the given values we have:

$4 (5) ^ 2 * 4-6 =\\4 (25) (4) -6=\\400-6 =\\394$

Finally, the value of the expression is 394.

Answer:

The value of the expression is 394.
