Question

If one zero of 4u² + 8u is -2 then find the another zero .

Answer 1

Given :-

One of the zeroes of 4u² + 8u is -2

To find :-

The another zero.

Solution :-

Given quardratic polynomial is 4u²+8u

To get zeroes of p(x) then we can write it as

p(x) = 0

Therefore, 4u²+8u = 0

=> 4u(u+2) = 0

=> 4u = 0 or u+2 = 0

=> u = 0/4 or u = -2

Therefore, u = 0 and -2

The other zero is 0

Answer :-

The another zero of 4u²+8u is 0

Answer 2

Given,

p(x) = 4u² + 8u , and one of the zero

$\tt \alpha = - 2$

Find other zero

Solution :-

by factorising the given polynomial,

$\rm⇢ \: \: 4u ^{2} + 8u = 0$

$\rm⇢ \: \: 4u(u + 2) = 0$

then,

$\rm⇢ \: \: 4u = 0$

$\rm⇢ \: \: u = \frac{0}{4}$

$\textbf{\textsf{ \orange⇢ \: \: \green{u = 0}}}$

FINAL ANSWER :-

Other zero of p(x) is 0 .
