b)x la puterea 2 -10 x +9= x la puterea 2 -9x-x+9= x(x-9)-1(x-9)= (x-1)(x-9)

c) ma mai gandesc

d) x la puterea 2 -8x -9= x la puterea 2 -9x+x-9= x(x-9)+1(x-9)=(x+1)(x-9)

e) x la puterea 2  -14 x+ 24= x la puterea 2 -12x-2+24=x(x-12)-2(x-12)=(x-2)(x-12)

f) x la puterea 2- -7x+10= x la puterea 2 -5x-2x+10= x (x-5)-1(x-5)=(x-1)(x-5)

g)x la puterea 2 -15x+56 =x la puterea 2-7x-8x+56=x(x-7)-8(x-7)=(x-8)(x-7)

h) x la puterea 2 +23x+60= x la puterea 2 +20x+3x+60=x(x+20)+3(x+20)=(x+3)(x+20)

i) x la puterea 2 +17x-60= x la puterea 2 +20x-3x-60= x(x+20)-3(x +20)=(x-3)(x+20)
