Question 1152328
the quadratic equation whose roots are {{{x[1]=-4}}} and {{{x[2]=1}}} and who's leading coefficient is {{{a=5}}} will be:

{{{f(x)=a(x-x[1])(x-x[2])}}}

{{{f(x)=5(x-(-4))(x-1)}}}
{{{f(x)=5(x+4)(x-1)}}}
{{{f(x)=5(x^2 + 3x - 4)}}}
{{{f(x)=5x^2 + 15x - 20}}}=> answer


{{{ graph(600, 600, -10, 10, -35, 10, 5x^2 + 15x - 20) }}}
