▶⏩ x² + 7x + 12.

→ a = 1; b = 7; c = 12.

=> Factorise this quadratic equation:-)

↪➡ x² + 4x + 3x + 12 = 0.

↪➡ x(x + 4) + 3(x + 4) = 0.

↪➡ (x + 3) ( x + 4)= 0.

=> x + 3 = 0. | x + 4 = 0.
=> x = -3. | x = -4.
=> œ = -3. | ß = -4.
[ œ = alpha , and ß = beta].

▶⏩ Hence, zeros of polynomial are -3 and -4.✔✔

▶⏩ Verification:-)⤵⤵⤵⤵⤵⤵

→ we know that :-)

=> œ + ß = -b/a.

[ Put the value of œ and ß ].

↪➡ -3 + (-4) = -7/1.

↪➡ -3 -4 = -7.

↪➡ -7 = -7.✅✅.

✴✴ Hence, it is verified ✴✴.
