the quadratic equation whose roots are
x%5B1%5D=-3 and
x%5B2%5D=1,
f%28x%29=a%2A%28x-x%5B1%5D%29%28x-x%5B2%5D%29
since given that leading coefficient is+1, a=1
f%28x%29=1%2A%28x-x%5B1%5D%29%28x-x%5B2%5D%29.......substitute given roots
f%28x%29=%28x-%28-3%29%29%28x-1%29
f%28x%29=%28x%2B3%29%28x-1%29
f%28x%29=x%5E2+%2B+2x+-+3
