The equation 4x2 + 8x + 15 = 0 is being rewritten in vertex form. Fill in the missing step.

Given4x2 + 8x + 15 = 0
Step 14(x2 + 2x ___) + 15 ___ = 0
Step 2✔
Step 34(x + 1)2 + 11 = 0
4(x2 + 2x + 1) + 15 − 4 = 0
4(x2 + 2x + 1) + 15 − 1 = 0
4(x2 + 2x + 2) + 15 − 2 = 0
4(x2 + 2x + 4) + 15 − 4 = 0

Two fire-lookout stations are 190 miles apart, with station a directly south of station b. both stations spot a fire. the bearing of the fire from station a is upper n 55 degrees upper e and the bearing of the fire from station b is upper s 60 degrees e. how far, to the nearest tenth of a mile, is the fire from each lookout station?
