Answer:
Q1.
a) 5.1 = (5.1)² = 26.01
b) (p-3q) = (p-3q)² = p²+9q²-6pq
Q2.
a) 103×107 = 11021
b) (x-9) (x+11) = x²+2x-99
Step-by-step explanation:
Q1. a) (5.1)² = 5.1× 5.1 = 26.01
b) (p-3q)² = p²+3q²-2×p×3q
= p²+9q²-6pq
Q2. a) 103×107 = (100+3)(100+7)
=(100)²+(3+7)×100+3×7
= 10000+1000+21
= 11021
b) (x-9) (x+11) = (x²)+(-9+11)×x +(-9×11)
= x²+2x+(-99)
= x²+2x-99
May it help you!
