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(x2)^2=3

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
