1. Yes x^2 + 4x + 4 - 4 + 3 = 0 is still equivalent to x^2 + 4x + 3 = 0 since whilst we have added a 4 to the function, we have also subtracted a 4, and since +4 - 4 = 0, we haven't actually changed the value of the equation

2. -1 is the sum of -4 and 3

3. (x + 2)^2 - 1 = (x + 2 + sq.root of 1)(x + 2 - sq.root of 1)
= (x + 2 + 1)(x + 2 - 1)
= (x + 3)(x + 1)
(x + 3)(x + 1) = 0
x = -3 or x = -1

Hope that makes sense :)

A pie has been in the oven for some number of minutes. it needs to bake for a total of 60 minutes. for how many more minutes mus
Lesechka [4]

The pie must stay for 60 - x more minutes must the pie bake

<h3>For how many more minutes must the pie bake?</h3>

Let the amount of time spent in the oven be x

So, we have

Total amount of time = 60 minutes

This means that

Remaining time + Amount of time spent = 60

This gives

Remaining time + x = 60

Evaluate

Remaining time = 60 - x

Hence, the pie must stay for 60 - x more minutes must the pie bake
