    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
