    2x² + 7x + 3 = 0

    Multiply first and last coefficients: 2*3 = 6

    We look for two numbers that multiply to give 6, and add to give 7

    Those two numbers are 1 and 6.

    Check: 6*1 = 6 6 + 1 = 7

    We replace the middle term of + 7x in the quadratic expression with 1x + 6x

    2x² + 7x + 3 = 0

    2x² + 1x + 6x + 3 = 0

    x (2x + 1) + 3 (2x + 1) = 0

    (2x + 1) (x + 3) = 0

    2x + 1 = 0 or x + 3 = 0

    2x = 0 - 1 x = 0 - 3

    2x = - 1 x = - 3

    x = - 1/2

    The solutions are x = - 1/2 or - 3.

    2x^2 + 7x + 3 = 0

    (2x + 1) (x + 3) = 0

    2x+1 = 0 x + 3 = 0

    2x = - 1 x = - 3

    x = - 1/2

    x = - 1/2 and - 1
