Question

the two number whose sum is 200 & there multiplication is 1025​

Answer 1

Answer:

first number : 205

second number : -5

Step-by-step explanation:

let be no 1 = X

let be no 2 = y

X+y = 200

XY = -1025

On solving X+y = 200 we get y = 200-x

putting value in second equation

X(200-x)=-1025

200x-x^2=-1025

0=x^2-200x-1025

0=x^2-205x+5x-1025

0=X(x-205)+5(x-205)

0=(x-205)(X+5)

X=205

X=-5
