What is the first step in solving the quadratic equation  x2  – 40 = 0? a)  taking the square root of both sides of the equationb) adding 40 to both sides of the equationc)  squaring both sides of the equationd)  subtracting 40 from both sides of the equation

First step in solving the quadratic equation x² – 40 = 0 is:

B) adding 40 to both sides of the equation

Step-by-step explanation:

We have to determine the first step in solving the following equation:

x²-40=0

Now, we begin solving the equation

x²-40=0

Adding 40 on both sides, we get:

x²-40+40=0+40

⇒ x²=40

Hence, first step in solving the quadratic equation x² – 40 = 0 is:

B) adding 40 to both sides of the equation
