Welcome to A-Maths!

In this blog, I will solve one more SAT math problem. I will solve this Question using the substitution method. How??

So, let's find out the answer,

You can see that our given function is

f(x) = (x+1)²

Our required value is

f(x+2)= ??

In order to solve this question, we will replace x with x+2 inside our given function and we will get

f(x+2) = (x+2+1)²

x+2 will come in the place of x.

Now just simplify 

f(x+2)= (x+3)²

Now you can see that this is becoming a+b whole square formula which is

(a+b)² = a² +2ab +b²

If a Is x and b is 3 we can write (x+3)² as

f(x+2)= x² + 2(x)(3) + 3²

f(x+2)= x² + 6x + 9

This is the solution to our given Equation. I hope this lesson will be very useful to all of you.
