Question

Zeros of p(x) = xsquare - 2x - 3 are
(a) 3 and 1
(c)-3 and -1
(b) 3 and -1
(d) 1 and -3​

Answer 1

$\:$

Answer:

The given quadratic polynomial: x²-2x-3=0

Factorising using middle term splitting,

=x²+x-3x-3=0

=x(x+1)-3(x+1)=0

=(x-3)(x+1)

Now,

x-3=0

x=3

Also

x+1=0

x=-1

Therefore, the correct answer is Option 3

Answer=> 3 and -1
