Question

if alpha and beta are the zeros of polynomial quadratic polynomial FX equal to 4 x square - 5 x minus 1 find the value of Alpha square beta and alpha beta square​

Answer 1

Answer:

-27/4

Step-by-step explanation:

F(x)=x^2-5x+4

Alpha + beta= -b/a= -(-5)/1=5

Alpha*beta=c/a=4/1=4

1/alpha+1/beta-2alpha*beta= (beta+alpha/alpha* beta) -2alpha* beta

=5/4-8

=(5-32)/4

= -27/4......
