Question 1176955


a root of multiplicity {{{2}}} at {{{x[1] = 1}}} =>{{{(x-1)^2}}}
a root of multiplicity {{{1}}} at{{{ x[2] = -1}}}=>{{{(x+1)}}}
 y-intercept is {{{y = -0.6}}}

{{{P(x)=a(x-1)^2*(x+1) }}}.........y-intercept is {{{y = -0.6}}}, or point ({{{0}}},{{{1}}}), use it to find {{{a}}}

{{{-0.6=a(0-1)^2*(0+1)}}}
{{{-0.6=a(1 )(1 )}}}
{{{a=-0.6}}}

then

{{{P(x)=-0.6(x^2-2x+1)*(x+1)}}}
{{{P(x)=-0.6(x^3 - x^2 - x + 1)}}}
{{{P(x)=-0.6x^3 +0.6x^2 +0.6x -0.6}}}
