Question

1. The zeroes of the quadratic polynomial 4x²-9​

Answer 1

Answer:

x = -3/2 and x = 3/2

Step-by-step explanation:

4x² - 9

= (2x)² - (3)²

= (2x + 3)(2x - 3) = 0

2x + 3 = 0

2x = -3

x = -3/2

and 2x - 3 = 0

2x = 3

x = 3/2

So, x = -3/2 and x = 3/2 are the zeroes of the quadratic polynomial 4x²-9​
