Answer:

HERE YOU GO MATE!

5x2−6x−2=0⇒x2−56x−52=0⇒x2−56x=52⇒x2−2×53x+(53)2

5x2−6x−2=0⇒x2−56x−52=0⇒x2−56x=52⇒x2−2×53x+(53)2⇒(x−53)2=2510+259⇒x−53=±519

5x2−6x−2=0⇒x2−56x−52=0⇒x2−56x=52⇒x2−2×53x+(53)2⇒(x−53)2=2510+259⇒x−53=±519⇒x=5±19

5x2−6x−2=0⇒x2−56x−52=0⇒x2−56x=52⇒x2−2×53x+(53)2⇒(x−53)2=2510+259⇒x−53=±519⇒x=5±19+3
