What is a factor of 144 − 49x²?

Solution:

An algebraic expression is a mathematical phrase that contains integral or fractional constants (numbers), variables (alphabets), and algebraic operators (such as addition, subtraction, division, multiplication, etc.) operating on them.

144 − 49x² [Given]

Now use the algebraic identity

a² - b² = (a + b) (a - b)

According to the formula

a = 12 and b = 7x

We can write it as

12² - (7x)² = (12 + 7x) (12 - 7x)

Therefore, the factor of 144 − 49x² is (12 + 7x) (12 - 7x).

What is a factor of 144 − 49x²?

Summary:

The factor of 144 − 49x² is (12 + 7x) (12 - 7x).
