Question

16x( 2 - x )+(4x - 5)² = 0

Answer 1

32х-16х²+16х²-40х+25=0 32х-40х+25=0 -8х+25=0 -8х=-25 х=258

Answer 2

огромное спасибо

Answer 3

а ты где живёш

Answer 4

(5+2y)(y-3)-2(y-1)²=0

Answer 5

32x-16x^2+16x^2-40x+25=0
32x-40x+25=0
-8x=-25
x= 25/8
x= 3 1/8

Answer 6

(5+2y)(y-3)-2(y-1)²=0

Answer 7

5y-15+2y^2-6y-2*(y^2-2y+1)=0; -y-15

Answer 8

упс сейчас допишу

Answer 9

-y -15 + 2y^2 - 2y^2 + 4 - 2=0; 3y-17=0; y= 17/3 y=5 2/3
