Question

The first three steps of completing the square to solve the quadratic equation 2? + 8x + 5 = 0 are shown

Answer 1

Answer:

see explanation

Step-by-step explanation:

take the square root of both sides

step 4 : x + 4 = ± $\sqrt{11}$ ( subtract 4 from both sides )

step 5 : x = - 4 ± $\sqrt{11}$

step 6 : x = - 4 - $\sqrt{11}$ , x = - 4 + $\sqrt{11}$

Answer 2

Answer:

x = 3/2

Step-by-step explanation:

Step 4: 2x + 8 = 11

step 5: 2x +8 - 8 = 11 -8

step 6: 2x/2 = 3/2

step 7: x = 3/2
