Х2 -4х-32=0
По теореме Виета.
x1+x2=-b
x1*x2=c
x1+x2=4
x1*x2=-32
х1=-4
x2=8
-4+8=4
4=4
-4*8=-32
a=1
а* (х-х1)(х-х2)
х2 -4х-32=(x-(-4)*(x-8)=(x+4)*(x-8)
4х2 -15x + 9 =0
D=b^2-4ac=(-15)^2-4*4*(9)=225-144=81
x1=-b-√D/2a=15-9/8=6/8=3/4=0.75
x2=-b+√D/2a=15+√81/2*4=15+9/8=24/8=3
x1=0.75
x2=3
a=4
4х2 -15x + 9=4*(x-0.75)*(x-3)
