Final answer:
To factor the quadratic expression 15x² + 35x, we look for common factors that can be factored out. In this case, both terms have a common factor of 5x. Factoring out 5x, we get: 15x² + 35x = 5x(3x + 7).
Step-by-step explanation:
To factor the quadratic expression 15x² + 35x, we look for common factors that can be factored out. In this case, both terms have a common factor of 5x. Factoring out 5x, we get:
15x² + 35x = 5x(3x + 7)
So, the factored form of the quadratic expression is 5x(3x + 7).
