Tamil Nadu Board Solutions for Chapter: Algebra, Exercise 29: Exercise 3.16

Graph the following quadratic equation and state its nature of solutions:

$(2 x-3)(x+2)=0$

Draw the graph of $y=x^2-4$ and hence solve $x^2-x-12=0$.

Draw the graph of $y=x^2+x$ and hence solve $x^2+1=0$.

Draw the graph of $y=x^2+ 3x +2$ and use it to solve $x^2+2x +1=0$.

Draw the graph of $y=x^2+3x-4$ and hence use it to solve $x^2+ 3x-4=0$.

Draw the graph of $y= x^2-5x -6$ and hence solve $x^2-5x -14=0$.

Draw the graph of $y=2x^2-3x-5$ and hence solve $2x^2-4x-6=0$.

Draw the graph of $y=(x-1)(x+3)$ and hence solve $x^2-x-6=0$.
