Question

find the zeros if quadratic polynomnial x^2-15​

Answer 1

Answer:

If we want to compute the zero of a polynomial f(x) , we need to set it equa to zero and solve it. One of the important algebraic rule we've used in this problem is (a2−b2)=(a+b)(a−b). ( a 2 − b 2 ) = ( a + b ) ( a − b ) .

Step-by-step explanation:

Answer 2

Answer:

${x}^{2} - 15 = 0$

${x}^{2} = 15$

$x = + \sqrt{15} \: or \: - \sqrt{15}$
