Hey mate here's your answer
let the two numbers be x and y
According to question -
Equation 1 ----
x + y = 15
x = 15 - y
Equation 2 ---
x × y = 26
Now put value of x in equation 2
15 - y × y = 26
15y - y^2 = 26
y^2 -15y + 26 = 0
y^2 -13y-2y+26 = 0
y(y- 13) - 2 ( y - 13 ) = 0
y = 13
y = 2
Now put value of y in equation 1
x = 15 - 13
x = 2
