Question

find the zeroes of the quadratic polynomial x²-7x

Answer 1

thank you this will help you the zeros of quadratic polynomial 0 and 7 ..

Answer 2

p(x) = x² - 7x

p(x) = ( x )² - ( √7 )²

$<u>a² - b² = ( a + b ) ( a - b )</u>$

Here, a = x, b = √7

p(x) = ( x + √7 ) ( x - √7 )

Now,

To find the zeroes, p(x) = 0

•°•

( x + √7 ) ( x - √7 ) = 0

Using zero product rule.

x = √7, - √7

$<b>Zeroes are ±√7.</b>$
