Question

if x = -2 is a root of the polynomial p(x) = -2x^4-7x^3-3x^2-tx-10. then find the value of t​

Answer 1

Answer:

hey mate here is your answer

p(x)= -2x^4 -7x^3 -3x^2 -tx -10

-2x^4- 7x^3 -3x^2- tx -10=0

on putting x= -2

-2 (-2)^4 -7(-2)^3 - 3(-2)^2 -t(-2)-10=0

-2(16)-7(-8)-3(4)+2+-10=0

-32+56+2+2t-10=0

56-54+2t=0

2+2t=0

2t=-2

t=-2÷2

t= -1

hence the value of it is -1
