Use Identities to Evaluate : (502)2

Use identities to evaluate : (502)²

Sum

(502)²
(502)²= (500 + 2)²
We know that,
( a + b )² = a² + b² + 2ab
∴ ( 500 + 2 )² = 500² + 2² + 2 x 500 x 2
= 250000 + 4 + 2000
= 2,52,004

Simplify the following products:

`(x/2 - 2/5)(2/5 - x/2) - x^2 + 2x`

If a² + b² + c² = 16 and ab + bc + ca = 10, find the value of a + b + c.

If 3x − 2y = 11 and xy = 12, find the value of 27x³ − 8y³

If \[x - \frac{1}{x} = \frac{15}{4}\], then \[x + \frac{1}{x}\] =

Use the direct method to evaluate :
(4+5x) (4−5x)

If a - b = 10 and ab = 11; find a + b.

Simplify:
(1 + x)(1 - x)(1 - x + x²)(1 + x + x²)

Factorise the following:

4x² + 20x + 25

Factorise the following:
