Answer:
x = - 13, x = - 3
Step-by-step explanation:
Given
x² + 16x = - 39
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(8)x + 64 = - 39 + 64
(x + 8)² = 25 ( take the square root of both sides )
x + 8 = ± = ± 5 ( subtract 8 from both sides )
x = - 8 ± 5, thus
x = - 8 - 5 = - 13 or x = - 8 + 5 = - 3
Answer:
Max is currently 12 years old.
Step-by-step explanation:
Zeke's current age = 8 years
Lets take Max's current age as years.
Then Max's age 3 years ago =
Double Max's age 3 years ago =
Double Max's age 3 years ago + Zee's current age = 26
⇒ +
=
=
= (Simplifying the brackets)
=
=
So Max's current age is 12 years.
