Now completing the square.

(x+5)² = 16 is the rewritten equation... For first question btw.
For the solutions to the equation -

x = -1,-9 is the solution, for the second question.
64 pages
divide 40 by 5 for pages printed in 1 minute then multiply this by 8
× 8 = 8 × 8 = 64 pages
In 5 years one California Palm tree grew = 85 inches.
Then in 1 year the California palm tree grew = (85/5) inches
= 17 inches
Again
A queen palm tree in 8 years grew = 96 inches
In 1 year the queen palm tree grew = (96/8) inches
= 12 inches.
So the California palm tree is growing at a faster rate than the queen palm tree. This is the easiest way of solving this kind of problems. Hope that i have explained the problem enough for you to understand and attempt such problems in the future without anyone's help.
