Use the identify (a + b) (a – b) = a2 – b2 to find the product.(3x

1.	Use the identify (a + b) (a – b) = a2 – b2 to find the product.(3x + 5) (3x – 5)
Answer» (a + b) (a – b) = a² – b² Here a = 3x, b = 5 (3x + 5)(3x – 5) = (3x)² – (5)² = 9x² -25

Use the identify (a + b) (a – b) = a2 – b2 to find the product.(3x + 5) (3x – 5)

Answer»

(a + b) (a – b) = a² – b²

Here a = 3x, b = 5

(3x + 5)(3x – 5) = (3x)² – (5)²

= 9x² -25
