Answer 2

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!
