Answer:
\sqrt{25} In its simplist form is 5.
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
if : n = 2 : 15 - n = 15 - 8 = 7
X3-7x=6x-12
x3-7x-6x+12=0
x3-13x+12=0
(x-1)(x2+x-12)=0
Calculate delta of the second bracket:
delta = 1+4*12=49
sqrt(delta)=sqrt(49)=7
x_1=(-1-7)/2=-4
x_2=(-1+7)/2=3
(x-1)(x+4)(x-3)=0
Answear:
Roots: x=1, x=-4, x=3.
