Question

Find a if one zero of polynomial ax2+(a-4)x+3 is negative of other

Answer 1

$\pink{\huge{SOLUTION}}$

If one zero is negative of the other, then the zeroes will be

α , -α

We know that

$\alpha + \beta = \frac{ - b}{a}$

Using this, we get

$\alpha + ( - \alpha ) = \frac{ - (a - 4)}{a}$

$0 = \frac{ - a + 4}{a}$

$0 = - a + 4$

$a = 4$

Hence,

$\huge{\boxed{a=4}}$
