Answer:
Solution given:
Since it is a form of (a+b)²
we have
(a+b)²=a²+2ab+b²
here
a=x
b=b/2a
now
substituting value
x²+2*x*b/2a+(b/2a)²

Answer:
y = 3
x = - 3
Step-by-step explanation:
First we represent "x" through "y"
y = x + 6
x = y - 6
Then we substatute this value instead of "x" in the other formula, and so we get...
y = - 2x - 3
y = - 2(y - 6) - 3
y = - 2y + 12 - 3
3y = 9
y = 3
Now that we know "y" we can find out "x" by doing...
x = y -6
x = 3 - 6
x = - 3
