Question

Find the zeros of quadratic polynomial relationship between zeros and coefficient 100 x square - 81

Answer 1

Step-by-step explanation:

100x²- 81

(10x)² - (9)²

(10x+9) (10x-9)

x = -9/10 ; +9/10

Verifing the relation between zeroes and coefficient

alpha + beta = -b/a

-9/10 + 9/10 = 0/100

-9+9/10 = 0

0/10 = 0

0 = 0

: Hence, Verified

alpha × beta = c/a

-9/10 × 9/10 = -81/100

-81/100 = -81/100

: Hence, Verified
