Question

check whether 1,-1 and 1/4 are zeroes of the polynomial p(x)=4 x2+3x-1​

Answer 1

Answer:

Here is your answer hope it helps

Explanation:

Answer 2

Answer:

take p(x)=1

4x2 + 3x -1

4×(1)2+3×(1)-1

4+3-1

7-1

6

p(x) =1 is not the solution of this equation

take p(x)= -1

4x2+3x-1

4(-1)2+3(-1)-1

4-3-1

4-4

0

p(x)= -1 is the solution of this equation

take p(x)=1/4

4x2+3x-1

4(1/4)2+3(1/4)-1

4×1/16+3/4-1

1/4+3/4-1

take L.C.M. of 4, 4 , and 1=4

1+3-4/4=4-4/4 =0/4=0

p(x)=1/4 is also the solution of this equation.
