Question

The zeros of the quadratic polynomial $x^2+88x+125$ are

(a) both positive (b) both negative

(c) one positive and one negative (d) both equal

Answer 1

We know that,

In a quadratic expression $a{x}^2+bx+c=0$ If a, b, c will have the same sign, then both zeroes of the expression are negative

Compare given expression

$x^2+88x+125$ with $a{x}^2+bx+c$

a = 1 , b = 88 ,c = 125

All are positive sign,

Therefore, the for expression, both zeroes has a negative sign.

Option B ) is correct.
