Answer 1

Answer:

$<marquee scrollamount=10>pls follow me and mark as brainliest$

Step-by-step explanation:

$\sf\red{1){(2a - b)}^{2} } \\ \sf\purple{ = > {2a}^{2} + {b}^{2} - 2 \times 2a \times b } \\ \sf\purple{ = > {2a}^{2} + {b}^{2} - 4ab} \\ \sf\pink{2) {( p+ 9)}^{2} } \\ \sf\pink{ = > {p}^{2} + {9}^{2} + 2 \times p \times 9 } \\ \sf\pink{ = > {p}^{2} + 9 + 18p}$

$\large\boxed{ \fcolorbox{pink}{green}{mark \: as \: brainliest}}$

$\large\boxed{ \fcolorbox{red}{purple}{pls \: follow \: me}}$
