Question

If one zero of the quadratic polynomial x^2+x-2 is -2,find the other zero

Answer 1

Hey there!
Down here ⏬

$p(x) = x {}^{2} + x - 2$

Since, -2 is the zero of p(x), (x+2) is a factor of p(x)

✓ Divide p(x) by (x+2)
{ By long division, refer attachment)

✓ x-1 is the qouteint obtained.

$x - 1 = 0$

$x = 1$

Therefore, 1 is the other zero.

Hope helped.

Answer 2

Step-by-step explanation:

Hey there!

Down here ⏬

p(x) = x {}^{2} + x - 2p(x)=x

2

+x−2

Since, -2 is the zero of p(x), (x+2) is a factor of p(x)

✓ Divide p(x) by (x+2)

{ By long division, refer attachment)

✓ x-1 is the qouteint obtained.

x - 1 = 0x−1=0

x = 1x=1

Therefore, 1 is the other zero.

Hope helped.
