Question

Why are 1by 4 and -1zeroes of the polynomial p(x) equal to 4xsquare+3x-1

Answer 1

Step-by-step explanation:

1/4,-1

p(x)= 4x^2+3x-1

p(1/4) =4(1/4)^2+3(1/4)-1

= 4(1/16)-3/4-1

= 4-4=0

p(-1) = 4(-1)^2+3(-1)-1

=4-4=0

So,-1/4'-1 are zeroes of the polynomial

1/4,-1

p(x)= 4x^2+3x-1

p(1/4) =4(1/4)^2+3(1/4)-1

= 4(1/16)-3/4-1

= 4-4=0

p(-1) = 4(-1)^2+3(-1)-1

=4-4=0

So,-1/4'-1 are zeroes of the polynomial
