Question

) show that 2 and 3 are zeroes
of the polynomial 15x^2+x -6​

Answer 1

Answer:

Given:

p(x) = 3x² -5x-2

and zeros 2 and -1/3

To prove : they are the zeros

    we know that ,if 'a' is a zero of polynomial p(x) then p(a)=0.Thus, we have to substitute the given numbers in place of x

first ,take x= 2

p(x) = 3x²-5x-2

⇒ p(2) = 3(2²)-5*2-2

         = 3*4-10-2

         = 12-12

        = 0

Hence, 2 is a root (zero) of the given polynomial.

second case , take x = -1/3

p(x)=3x²-5x-2

Hence, -1/3 is another zero of the polynomial
