Answer:
The rectangle doesn't exists
Step-by-step explanation:
(4x+3).(x+1)= ?
4x² + 4x + 3x + 3 = ?
4x² + 7x + 3 = ?
4 = a
7 = b
3 = c
delta = b² - 4.a.c
delta = 7² - 4.4.3
delta = 49 - 4.4.3
delta = 49 - 48
delta = 1
x1 = -b + (square root)delta / 2.a
x1 = -7 + 1/2.4
x1 = -6 / 8
x2 = -7 - 1/2.4
x2 = -8/8
x2 = -1
