If a = 7, b = - 3 and c = 2, the 2nd degree equation that corresponds to these coefficients is: 2x (x+1) + 5x² - 5x = - 2 2x² + 7x - 5 = 0 3x² - 7 = 0 4 (x² + 7) - 3x - 7 = 0 None of the above.

    2x (x+1) + 5x² - 5x = - 2

    Step-by-step explanation:

    a=7

    b=-3

    c=2

    2nd degree equation is written as

    ax^2+bx+c=0

    2x (x+1) + 5x² - 5x = - 2

    2x^2+2x+5x^2-5x=-2

    Collect like terms

    2x^2+5x^2+2x-5x+2=0

    7x^2-3x+2=0

    a=7, b=-3, c=2

    Therefore, the 2nd degree equation that corresponds with the above coefficients is 2x (x+1) + 5x² - 5x = - 2
