FACTOR THE FOLLOWING DIFFERENCE OF SQUARES 169a^2-49b^2

Anonymous

169a^2 - 49b^2 = (13a + 7b)(13a - 7b)

169a^2 - 49b^2 = (13a + 7b)(13a - 7b)

Remember how the difference of squares is always factored: x² - y² = (x+y)(x-y) 169a² - 49b² = (13a)² - (7b)² = (13a+7b)(13a-7b)

Remember the rule for factoring a difference of squares: x² - y² = (x + y)(x - y) In your case: Let x = 13a Let y = 7b x² = (13a)² = 169a² y² = (7b)² = 49b² Hence: (13a + 7b)(13a - 7b)

I think this is what you're looking for: (13a + 7b) * (13a - 7b)
