Объяснение:

x² - 2x - 24 = 0

D = (-2)² - 4 * (-24) = 100

x² - 10x + 24 = 0

D = 4

x² + 2x - 24 = 0

D = 100

Ответ:

e)x²-2x-24=0

x²+4x-6-24=0

x*(x+4x)-6(x+4)=0

(x+4)*(x-6)=0

x+4=0

x-6=0

x=-4

x=6

ж)x²-10x+24=0

x²-4x-6x+24=0

x*(x-4)-6(x-4)=0

(x-4)*(x-6)=0

x-4=0

x-6=0

x=4

x=6

з)x²+2x-24=0

x²+6x-4x-24=0

x*(x+6)-4(x+6)=0

(x+4)*(x-4)=0

x+6=0

x-4=0

x=-6

x=4
