If two numbers are − 3 and − 5 , with sum − 8 and product + 15, then which is the correct algebraic expression?

Answer: x ^2 −8x+15
Explanation
  • Sum of two numbers: 3+(5)=8-3 + (-5) = -8

  • Product: (3)×(5)=+15(-3) times (-5) = +15

Let’s now write an algebraic expression where the sum is 8-8and the product is +15+15.

This is a quadratic expression of the form:

x2+8x+15x^2 + 8x + 15
