How do you factor x2 4x-80?

Answer 1

To factor the expression ( x^2 + 4x - 80 ), first look for two numbers that multiply to (-80) (the constant term) and add up to (4) (the coefficient of the linear term). The numbers (10) and (-8) fit this requirement. Thus, you can rewrite the expression as ( (x + 10)(x - 8) ). Therefore, the factored form of ( x^2 + 4x - 80 ) is ( (x + 10)(x - 8) ).
