Answer:
DID YOU MEAN:
p (x) = 1x²+3x+2
⟹Split the middle term to find the zeros.
The polynomial is in the form ax²+bx+c.
Step 1 - multiply a×c, i.e., 1×2=2.
What number when multiplied gives us 2 and when added gives us +3?
The answer is 2 and 1, because 2×1=2 and 2+1=3. Thus, we can write p(x) as:
1x²+2x+1x+2
x(x+2)+1(x+2)=0
(x+1)(x+2)=0
x=-1,-2
OR DID YOU MEAN:
P(x)=x²-3x+2
⟹Split the middle term to find the zeros.
The polynomial is in the form ax²+bx+c.
Step 1 - multiply a×c, i.e., 1×2=2.
What number when multiplied gives us 2 and when added gives us -3?
The answer is -2 and -1, because -2×-1=2 and -2-1=-3. Thus, we can write p(x) as:
1x²-1x-2x+2
x(x-1)-2(x-1)=0
(x-1)(x-2)=0
x=1,2
