Question

* The zeros of the quadratic polynomial 3x^2-48 are

1- Both negative
2- Both positive
3- One positive
4- Both equal​

Answer 1

Appropriate question:

• The zeros of the quadratic polynomial 3x^2-48 are?
• 1- Both negative
• 2- Both positive
• 3- One positive and one negative.
• 4- Both equal

GivEn:

• Quadratic polynomial is 3x² - 48.

To find:

• The zeros of the quadratic polynomial?

Solution:

Here,

• 3x² - 48 = 0

Therefore,

⇒3x² = 48

⇒x² = 48/3

⇒x² = 16

⇒x = √16

⇒x = ± 4

∴ Hence, The zeroes of the quadratic polynomial are one positive and one negative.
