Y=x²-6x+14
y=(x²-2*3x +3²-3²)+14
y=(x²-2*3x+3²)+14-9
y=(x-3)²+5
a=1
p=3
q=5
a>0 ⇒ vertex is minimum
V(p,q) ⇒ V(3;5)

X=-3X=2 —> move the variable to the left handed side and change its sign
-2x=2 —> collect like terms
Divide both sides of the equation by -2 and your answer is x=-1
Answer:
x=-8
Step-by-step explanation:
3/4x+5-1/2x=3
3x+20-2x=12
x+20=12
x=12-20
x=-8
Answer:
-2.23
