Question

expand (2x+3y+5)square​

Answer 1

$\star\;{\underline{\underline{\sf{\pink{QueStion\;\;:}}}}}$

$expand \: (2x+3y+5)^2$

$\huge\star{\underline{\mathtt{\red{A}\pink{N}</p><p>\green{S}\blue{W}\purple{E}\orange{R}}}}\star$

$(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca$

$(2x+3y+5)^2=4x^2+9y^2+25+12xy+30y+20x$

Answer 2

Answer:

(2x+3y+5)2

by using : a²+b²+c²+2ab+2bc+2ca=(a+b+c)

2x²+3y²+5²+2(2x*3y)+2(3y*5)+2(2x*5)

4x²+9y²+25+12xy+30y+20x

Step-by-step explanation:

simply use this formula and put the value given

{a²+b²+c²+2ab+2bc+2ca=(a+b+c)²]
