Use the Direct Method to Evaluate : (Ab+X2) (Ab−X2)

Use the direct method to evaluate :
(ab+x²) (ab−x²)

Sum

Note: (a+b) (a−b) = a² − b²

(ab+x²) (ab−x²) = (ab)² − (x²)²

= a²b² − x⁴

Exercise 12 (A) | Q 2.07 | Page 150

Evaluate the following using identities:

(1.5x²− 0.3y²) (1.5x²+ 0.3y²)

Write in the expanded form:

`(a/(bc) + b/(ca) + c/(ab))^2`

If \[x^4 + \frac{1}{x^4} = 119\] , find the value of \[x^3 - \frac{1}{x^3}\]

Find the following product:

(2ab − 3b − 2c) (4a² + 9b² +4c² + 6 ab − 6 bc + 4ca)

If a − b = 5 and ab = 12, find the value of a² + b²

The product (a + b) (a − b) (a² − ab + b²) (a² + ab + b²) is equal to

If a² - 3a + 1 = 0, and a ≠ 0; find:

Evaluate: (5xy − 7) (7xy + 9)

Simplify:
(7a +5b)² - (7a - 5b)²

Evaluate the following :
1.81 x 1.81 - 1.81 x 2.19 + 2.19 x 2.19
