А) (2х+1)²= 4х²+4х+1
Б) (3а-с)²= 9а²–6ас+с²
В) (а+6)(а-6)= а²–36
Г) (3х-4у) (3х+4у)= 9х²–16у²
№2
А) у²-¼= (у–½)(у+½)
Б) х²+10х+25= (х+5)²
№3
(2х-у)²-4х(х-у)= 4х²–4ху+у²–4х²+4ху= у²
при у= -⅔
(–⅔)²= 
ответ:
№4
А) 3(2а-b) (2a+b)= 3(4a²–b²)= 12a²–3b²
Б (х⁴+у³)² = (x^8)+2x⁴y³+(y^6)
В) (а+3b)²-(a-3b)²=(a+3b+a–3b)(a+3b–(a–3b))= a²(a+3b–a+3b)= a²*6b= 6a²b
№5
А) (2а-5)²-(2а-3) (2а+3)=0
(4a²–20a+25)–(4a²–9)=0
4a²–20a+25–4a²+9=0
–20a+34=0
20a=34
a= 
a= 1,7

(6c+7)²-c²=(6c+7-c)(6c+7+c) =(5c+7)(7c+7)
(5c+7)² /(5c+7)(7c+7) =(5c+7)/(7c+7)
b) 9p²-12pq+4q²=(3p -2q)²
q²-(3p-3q)²=(q-(3p-3q)(q+ (3p-3q)=(q-3p+3q)(q+3p-3q) =(4q -3p)(3p -2q)
(3p-2q)² /(4q-3p)(3p-2q) = (3p-2q) /(4q-3p)
