• 2 × (4 + 3)² - 14 × 3 = ??

$\\\:{ \color{purple}{\maltese}}\:\:\:{\large{ \underline{ \underline{\textsf{Solution \: :}}}}}$

$\\ \sf \implies \: 2 × (4 + 3)² - 14 × 3$

$\\ \sf \implies \: 2 × (7)² - 14 × 3$

$\\ \sf \implies \: 2 × 49 - 14 \times 3$

$\\\sf \implies \: 2 × 49 - 42$

$\\\sf \implies \: 98 - 42$

$\\ \sf \implies \: 56$

Answer 2

• 2(4+3)²-14(3)
• 2(7)²-42
• 2(49)-42
• 98-42.
• 56
