Question

x^2 + (x+2 )^2. pls solve it's urgent​

Answer 1

Answer: 2 (x^2+2x+2)

Step-by-step explanation:

x^2+x^2+4x+4

2x^2+4x+4

2 (x^2+2x+2)

Answer 2

ANSWER:

• Value of the above expression is 2(x²+2x+2)

GIVEN:

• x²+(x+2)²

TO FIND:

• Value of the above expression.

SOLUTION:

= x²+(x+2)²

= x²+(x)²+(2)²+2(x)(2)

= x²+x²+4+4x

= 2x²+4x+4

= 2(x²+2x+2)

Value of the above expression is 2(x²+2x+2)

NOTE:

Some important formulas:

(a+b)² = a²+b²+2ab

(a-b)² = a²+b²-2ab

(a+b)(a-b) = a²-b²

(a+b)³ = a³+b³+3ab(a+b)

(a-b)³ = a³-b³-3ab(a-b)

a³+b³ = (a+b)(a²+b²-ab)

a³-b³ = (a-b)(a²+b²+ab)

(a+b)² = (a-b)²+4ab

(a-b)² = (a+b)²-4ab
