Q. 5(2)(−3)+(2)2−2(−3)25(2)(-3)+(2)^2-2(-3)^2
  1. Calculate 5(2)(−3)5(2)(-3): Calculate 5(2)(−3)5(2)(-3).5×2×−3=−305 \times 2 \times -3 = -30
  2. Calculate (2)2(2)^2: Calculate (2)2(2)^2.22=42^2 = 4
  3. Calculate −2(−3)2-2(-3)^2: Calculate −2(−3)2-2(-3)^2.\newline−2×(−3)2=−2×9=−18-2 \times (-3)^2 = -2 \times 9 = -18
  4. Add all the results together: Add all the results together.\newline−30+4−18=−44-30 + 4 - 18 = -44
