Question

(2x+5)²=93 sole with factorization method​

Answer 1

Answer:

Let's solve your equation step-by-step.

(2x+5)^2=93

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

        4x^2+20x+25=93

Step 2: Subtract 93 from both sides.

        4x^2+20x+25−93=93−93

        4x^2+20x−68=0

Step 3: Use quadratic formula with a=4, b=20, c=-68.

        x  =   −b  ±  {√b^2−4ac}  / 2a

        x  =    −(20)   ±  {√(20)^2−4(4)(−68) }   /   2(4)

         x   =    (−20±[√1488])  / 8

          x  =    −5  / 2 + 1  / 2 (√93)        or     x=    −5 /  2 +{ −1   / 2 (√93) }

Answer:

             x= (−5 / 2 )+ 1 /  2 (√93)       or    

                                             x=( −5  / 2) + {−1 /  2 (√93)}
