Answer:
(x + 2)² = 16
Step-by-step explanation:
Given
x² + 4x = 12
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 12 + 4, that is
(x + 2)² = 16
1207838929299236636236+2892
Say that xyz is your number, then y=4z and x+3=y
Since it is a multiple of 4, y has to be 4 or 8, which means z has to be 1 or 2, since it is 1/4 of y and then since x is 3 less than y, x would have to be 1 or 5...so the numbers are....141 or 582
