Решите уравнения 1) (3x-4)2+4x=9x2-24 2) (2x-3)2-x(4x+5)-8=o

(3x-4)²+4x= 9x² -24
(3x)²-2*3x*4+4² +4x = 9x²-24
9x²- 24x +16+4x -9x²+24=0
-20x +40=0
-20x=-40
x= -40/(-20)
x= 2

(2x-3)²-x(4x+5) -8=0
4x²-12x+9 -4x²-5x-8=0
-17x +1=0
-17x=-1
17x=1
x= 1/17

(3х-4)²+4х=9х²-24
9х²-24х+16+4х-9х²+24=0
-20х+40=0
-20х=-40
х=2

(2х-3)²-х(4х+5)-8=0
4х²-12х+9-4х²-5х-8=0
-17х+1=0
-17х=-1
х=1/17
