Which of the following would be the most logical first step to solving this
quadratic equation?
x2 - 4x + 16 = 2
a. take the square root of both sides.
b. subtract 2 from both sides.
estate
c. factor the left side into a perfect square.
d. divide both sides by x

The correct option is B:

Subtract 2 from both sides

Step-by-step explanation:

We have the equation x²-4x+16=2

The first step to solve this equation is:

Subtract 2 from both sides

We get;

x²-4x+16=2

x²-4x+16-2=2-2

x²-4x+14=0

Now this is the quadratic equation. You can use quadratic formula to solve this equation

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
