Question

if the zero of the polynomial p(x) = x3 +3x2 +4x -11 are a,band c and the zeroes of the polynomial q(x)= x 3 +rx2 +sx +t are a+b,b+c and c+a then find t

Answer 1

p(x)= x³+3x²+4x-11
p(1)= (1)³+3(1)²+4(1)-11
= 1+3+4-11
= -3
(ans)

Answer 2

P(x) = x³+3x² - 4x - 11
p(1) =(1)³+3(1)²-4(1) -11
= 1+3-4-11
= 4-15
= -11
put the value of p(x)in 2nd equation .
