Question

21. Find a zero of the polynomial p(x) = 2x + 1.

22. 2 3 + 3 is equal to----

23. For what value of c, the linear equation 2x + cy = 8 has equal values of x and y for its

solution.

24. In which quadrant or on which axis the point (– 3, 5) lie.​

Answer 1

Step-by-step explanation:

21. p(X)=2x+1

let, X + 1 =0

X = -1

therefore, X = -5 is zero of the polynomial p(X)= X+5.
