write the quadratic equation whose roots are -5 and -4, and whose leading coefficient is 1. (Use the letter x to represent the variable)

Question

write the answer in _= 0

Answer 1

When the leading coefficient is 1, the equation will be (x-x1) (x-x2) = 0, where x1, x2 are the roots

So here x1=-5, x2=-4 so the equation is (x+5) (x+4) = 0

Multiplying out gives x² + 9x + 20 = 0
