Question

23.Find the zeroes of the quadratic polynomial: a²-25

Answer 1

Answer:

The zeroes of the given quadratic formula are 5 and -5.

Step-by-step explanation:

A quadractic polynomial is an equation where the highest power of the variable is 2, a quadratic equation is formed when a quadractic polynomial is equated to zero.

Zeroes of a quadratic formula mean the points on curve that intersect the x-axis, to find zeroes of a quadratic polynomial we need to equate the polynomial to zero.

$a^{2}-25=0\\(a+5)(a-5)=0$

which means:

a+5=0   or      a-5=0

a=-5      or       a=5

therefore the zeroes of the quadratic polynomial are 5 and -5.
