Question

Find the zero of the polynomial (x+1) (x+3)

Answer 1

Answer:

$(x + 1)(x + 3) \\ = if \\ x + 1 = 0 \\ x = - 1 \\ if \\ x + 3 = 0 \\ x = - 3$

therefore zeroes are -1 and -3....☺️

Answer 2

Answer:

(x+1)=0

x=-1

then,(x+3)=0

x=-3

So, the zeros of polynomial (x+1)(x+3) are -1 and -3.
