Question

right in expanded form (3l - 2m + 5n)^2​

Answer 1

Step-by-step explanation:

(3l - 2m + 5n)(3l - 2m + 5n)

Answer 2

$\sf\Large{\underline{\underline{Question}}}:-$

Write in expanded form:

$\sf \: (3l - 2m + 5) {}^{2}$

$\sf\Large{\underline{\underline{Solution}}}:-$

$\sf \: (3l - 2m + 5) {}^{2}$

= (3l - 2m + 5n) (3l - 2m + 5n)

= 9l² - 6lm + 15ln - 6lm + 4m² - 10mn + 15ln - 10mn + 25n²

= 9l² + 4m² + 25n² - 12lm + 30ln - 20mn
