1) 2х+6-ху-3у= 2(х+3)-у(х+3) = (х+3)(2-у)
2х²+2-х³-х⁵ = 2(х²+1)-х³(1+х²) = (х²+1)(2-х³)
2)
= 0,232(0,114-0,232+0,118) = 0,232(0,114+0,118-0,232) = 0,232*0 = 0
3)9а²-16 = (3а+4)(3а-4)
16m²-81n²=(4m+9n)(4m-9n)
4)
(3x+4)²-16 = 0
(3x+4+4)(3x+4-4) = 0
(3x+8)*3x=0
3x=0 3x+8=0
x=0 3x=-8
x = -8/3
5)
3х³+6х² = 12х+24
3х²(х+2) = 12(х+2)
3х²(х+2) - 12(х+2) = 0
(х+2)(3х²-12)=0
х+2 = 0 3х²-12=0
х = -2 3х²=12
х² = 4
х = 2
х = -2
