Q1 of 157 Page 30

Choose the correct answer for the following:
The factors of 3a + 21ab are _______

Given 3a + 21ab can be written as 3× a× (1 + 7b)

If (x + a) (x + b) = x² – 5x – 300, find the values of a² + b².

Deduce the Algebraic identity for (x + a) (x + b) (x + c) by using the product formula. [Hint: (x + a) (x + b)(x + c) = (x + a) [(x + b)(x + c)]]

Choose the correct answer for the following:
