Question

draw graph of polynomial x2+4x+3 and find the zeros

Answer 1

Answer:

Step-by-step explanation:

Answer 2

x²+4x+3=0

By factorisation method:-

Sum = 4(3+1)

Product= 1×3=3

ax²+bx+c=0

x²+(3+1)x+3=0

x²+3x+1x+3=0

Taking common

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

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

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

x= -1 or x= -3

Zeros are -1 and -3.
