P²-12p-49=-103
add 49 to both sides
p²-12p=-54
take 1/2 of the linear coefient and square it
-12 is the linear coefitnt so -12/2=-6, (-6)²=36
add 36 to both sides
p²-12p+36=-18
factor perfect square trinomial
(p-6)²=-18
square root both sides
no solution because we can't squaer anything and get a negative
X²+v=w (move v to w)
x²=w-v
x=√w-v (then square root w-v)
Step-by-step explanation:
3(m-2)-5=8-2(m-4)
- 3m-6-5=8-2m+8
- 3m-11=16-2m
- 3m+2m=16+11
- 5m=27
- m=27/5
- m=5.4
