We are given that in the quadratic equation ax^2+bx+c, a,b,c are terms of arithmetic sequence such that a = 2t-3, b = 5t+1 and c = 4t-7
As consecutive terms of an AP have a common difference:
4t - 7 - 5t - 1 = 5t + 1 - 2t...

We are given that in the quadratic equation ax^2+bx+c, a,b,c are terms of arithmetic sequence such that a = 2t-3, b = 5t+1 and c = 4t-7
As consecutive terms of an AP have a common difference:
4t - 7 - 5t - 1 = 5t + 1 - 2t + 3
=> -t - 8 = 3t + 4
=> 4t = -12
=> t = -3
a = 2t - 3 = -6 - 3 = -9
b = 5t + 1 = -15 + 1 = -14
c = 4t - 7 = -12 - 7 = -19
The quadratic equation is -9x^2 - 14x - 19 = 0
=> 9x^2 + 14x + 19 = 0
The required quadratic equation is 9x^2 + 14x + 19 = 0
