Answer 1

Step-by-step explanation:

Ques 1

(5-2x)(3+x)

= 5(3+x)-2x(3+x)

= 15+5x-6x-2x²

= 15-1x-2x² (ans.)

Ques2

ans= p²+pq+q²-qr+r²-rp

Ques 3

ans= 9l²-55ln

Ques4

ans=

$(a - b)^{2} = {a}^{2} - 2ab \: + {b}^{2}$

(6x²)² - 2 (6x)(5y) + (5y)²

36x²-60xy + 25y²

Ques 5

(9.8)²

(10-0.2)²

10²-2×10×0.2+ 0.2²

100-4+0.04

96.04 (ans)
