Answer:
12 to 8, 6 to 4
Step-by-step explanation:
We can factor the equation into:
(x-10)*(x-3)
Therefore the roots are:
X = 10
X = 3
Answer:
-13,1
Step-by-step explanation:
f(x)= (x+6)^2-49
When we find the zero's we set f(x) =0
0= (x+6)^2-49
Add 49 to each side
49= (x+6)^2-49+49
49= (x+6)^2
Take the square root of each side
±sqrt(49) = sqrt((x+6)^2)
±7 = (x+6)
Subtract 6 from each side
±7-6 = (x+6-6)
±7-6 = x
7-6 =x -7-6 =x
1=x -13=x
Cross multiply by 10 then divide by 3 to get 4/3
