Answer:
(2x-9)(2x+9)
Step-by-step explanation:
This is a difference of squares because it can be written as (2x)^2-9^2
The formula for factoring a difference of squares is a^2-b^2=(a-b)(a+b)
So replace a with 2x and b with 9 giving us
4x^2-81=(2x-9)(2x+9)
Answer:
Let number of weeks be x
10x = 200-150
x=50/10
x=5
Thus it would take him 5 weeks to buy himself a iPhone12
