What Two numbers multiply to get 20 and add to get 17?

Answer:1.2715815.72842Step-by-step explanation:

Step-by-step explanation:x + y = 17x = 17 - yxy = 20(17 - y)y = 20-y² + 17y = 20-y² + 17y - 20 = 0the general solution to such a quadratic equationax² + bx + c = 0isx = (-b ± sqrt(b² - 4ac))/(2a)in our casey = (-17 ± sqrt(17² - 4×-1×-20))/(2×-1) = = (-17 ± sqrt(289 - 80))/-2 = = (-17 ± sqrt(209))/-2y1 = (-17 + sqrt(209))/-2 = 1.271583853...y2 = (-17 - sqrt(209))/-2 = 15.72841615...the 2 numbers are1.271583853...15.72841615...
