Use the difference of squares identity to write this polynomial expression in factored form: 9x2 − 49.

Step-by-step explanation:

Use the difference of squares identity to write this polynomial expression in factored form:  

Difference of square formula is

9 can be written as 3^2

49 can be written as 7^2

The value of 'a' is 3x  and b is 7

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

a)(x-2)^2+(y-1)^2=9
