Question

विस्तार करा: (2p + q + 5)²

Answer 1

विस्तार सूत्र:

${(x + y + z)}^{2} = {x}^{2} + {y}^{2} + {z}^{2} + 2xy + 2yz + 2xz$
$x = 2p \\ \\ y = q \\ \\ z = 5$
${(2p+q+5)}^{2} = {(2p)}^{2} + {(q)}^{2} + {(5)}^{2} \\ \\ + 2(2p)(q) + 2(q)(5) + 2(5)(2q) \\ \\ = 4{p}^{2} + {q}^{2} + 25 + 4pq + 10q + 20q$
विस्तार:

${(2p+q+5)}^{2} =4{p}^{2} + {q}^{2} + 25 + 4pq + 10q + 20q$

Answer 2

Answer:

4p²+q²+25+4pq+10q+20p.

Step-by-step explanation:

a=2p

b=q

c=5

formula-

(a+b+c)²= a²+b²+c²+2ab+2bc+2ca

(2p+q+5)²= (2p)²+q²+5²+(2*2p*q)+(2*q*5)+(2*2p*5)

= 4p²+q²+25+4pq+10q+20p.
