Answer» Answer: 973162 Step-by-step explanation: 991 × 982 = (1000-9)(1000-18) Using the IDENTITY (x+a)(x+b) = x²+(a+b)x+ab Here x=1000, a=(-9), b=(-18) (1000-9)(1000-18)= (1000)²+[-9+(-18)]1000+[(-9)(-18)] = 1000000+(-27)1000+162 = 1000000+(-27000)+162 = 1000000-27000+162 = 973000+162 = 973162 HOPE ITS HELPFUL!!

Answer:

973162

Step-by-step explanation:

991 × 982 = (1000-9)(1000-18)

Using the IDENTITY (x+a)(x+b) = x²+(a+b)x+ab

Here x=1000, a=(-9), b=(-18)

(1000-9)(1000-18)= (1000)²+[-9+(-18)]1000+[(-9)(-18)]

= 1000000+(-27)1000+162

= 1000000+(-27000)+162

= 1000000-27000+162

= 973000+162

= 973162
