1. solve by using the quadratic formula. 5x^2+x=3
2. solve by completing the square. x^2=5x+2
3.solve by using the square roots method. 5(x-2)^2=3

  • math -

    are you studying quadratic equations?

    If so, then I am surprised that you cannot do these straightforward questions.
    Do you not have a textbook?

    I will do the first one

    5x^2+x=3
    5x^2 + x - 3 = 0

    x = (-1 ±√(1 - 4*5*(-3))/10

    x = (-1 ±√61)/10
