To factor an expression is to rewrite the expression in a factored form
The factored expression of 15ab + 24bc is 3b(5a + 8c)
The expression is given as:
15ab + 24bc
Factor out b from the expression
15ab + 24bc = b(15a + 24c)
Factor out 3 from the expression
15ab + 24bc = 3b(5a + 8c)
The expression can no longer be factorized.
Hence, the factored expression of 15ab + 24bc is 3b(5a + 8c)
