Quadratic equation is

#### Explanation:

Le the quadratic equation be

as

**...........(1)**

and **...........(2)**

As it passes through

**...........(3)**

Subtracting (2) from (1), we get **........(4)**

and subtracting (3) from (1), we get **...........(5)**

Subtracting (4) from (5), we get

Putting this in (4), we get

and putting

Hence quadratic equation is

graph{y=x^2+3x-4 [-12.21, 7.79, -6.48, 3.52]}
