Question

Expand of (2p+p+5) ^2​

Answer 1

Answer:

9p² + 30p + 25

Step-by-step explanation:

Answer 2

Given :-

$\sf {(2p + p + 5)}^{2}$

To :-

Expand the above expression

Solution :-

$\sf {(2p)}^{2} + {(p)}^{2} + {(5)}^{2} <u> </u>+ 2(2p)(p) + 2(p)(5) + 2(5)(2p)$

→$\sf {4p}^{2} + {p}^{2} + {25}^{2} + <u> </u>{4p} + 10p + 20p$

Procedure :-

→ This question is from Algebraic identites.

→ The above expression will be solved by using Identity 5th which is (a+b+c)² = a² + b² + c² + 2ab + 2bc + 2ca.

→ First we will do the square of 2p , p and 5 and then we will first the constants which are their in brackets and then we will multiply it by 2 which is outside the bracket.
