The given quadratic equation is ;
3x² + 12 - 13x = 0.
The given quadratic equation can be rewritten as ; 3x² - 13x + 12 = 0.
Now,
Comparing the above equation with the general quadratic equation ax² + bx + c = 0,
We have;
a = 3
b = -13
c = 12
Thus,
The ratio of sum and product of the roots of given quadratic equation will be -b/c
-b/c = -(-13)/12 = 13/12.

Let the first no = x Second number = y according to the question - 17-y=3x - (1) Y+ 19 = 3x -(2) From eq (1) 17-y/3 = x - (3) Substitute equation(3) in (2) y+19= 3(17-y/3) y+19 = 17-y y +y = 17-19 2y = -2 y = -2/2 y = -1 Put y=-1 in equation (1) 17-(-1) = 3x 17+1 = 3x 18 =3x 18/3 =x x=6 Therefore, x=6 and y= -1
