1/4 + 1/2 + x = −3/4
get a common denominator 1/4
1/4 +2/4 +x = -3/4
combine like terms
3/4 +x =-3/4
subtract 3/4 from each side
x = -3/4 -3/4
x = -6/4
divide top and bottom by 2
x = -3/2
x = -1 1/2
Answer : x = -1 1/2
Answer:
348
Step-by-step explanation:
X^2 + 12x + n

x^2 + 12x + 6^2
n = 36
(x + 6)^2 will give you a perfect square.
