упростите выражение
4ав + 2(а-в)в квадрате
(а-4)в квадрате - 2а(3а-4)
4ab+2(a^2-2ab+b^2)=4ab+2a^2-4ab+b^2=2a^2+b^2
a^2-8a+16-6a^2+12a=-5a^2+6a+16
1)4ab + 2(a-b)^ = 4ab + 2(a^ - 2ab + b^)= 4ab + 2a^ - 4ab + 2b^= 2a^ + 2b^= 2(a^+ b^)
2) (a-4)^ - 2a(3a-4)= a^ - 8a + 16 - 6a^ + 8a= a^ + 16 ну или (a-4)(a+b)
