Question

Check whether 1.-1 and
4
are zeroes of the polynomial p(x) = 4x^2 - 3x-1.​

Answer 1

Answer:

it was a good question

but don't worry I don't no answer

Answer 2

Answer:

p(x) =4x²-3x-1

p(1)=4(1)²-3×1-1

p(1)=4-3-1

p(1)=4-4

p(1)=0

p(x)=4x²-3x-1

p(-1)=4(-1)²-3(-1)-1

p(-1)=4×1+3-1

p(-1)=4+3-1

p(-1)=7-1

p(-1)=6

p(x)=4x²-3x-1

p(4)=4(4)²-3×4-1

p(4)=4×16-12-1

p(4)=64-13

p(4)=51

Therefore 1 is zero of the polynomial 4x²-3x-1

and - 1 and 4 are not the zeroes of the polynomial 4x²-3x-1
