0x-34 = -34
12x^3+17x^2+5x=0x(12x^2+17x+5)=0x(x+1)(12x+5)=0x=0x=-1x=-5/12
x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8
x2 - 5x = 0x (x - 5) = 0x = 0andx = 5
x+(-2.5)+6.8=0x+(-2.5+6.8)=0x+(4.3)=0x+4.3=0Subtract 4.3 from both sides and you get:x= -4.3
x2 - 13x = 0x (x - 13) = 0x = 0andx = 13
X2+0X - 2.25=01.= Both sides by 2.25X2+0X=2.252. Subtract both sides by 0XX2=2.253. Square root both sidesX=1.5
x2 - 5x = 0Factor the left side:x (x - 5) = 0x = 0x = 5
x3+13x2=-22xadd 22x to both sides:x3+13x2+22x=0now factor:x(x2+13x+22)=0x(x+11)(x+2)=0x=0x+11=0x+2=0Therefore the solution to this equation is x=0, x=-11, x=-2
x+1=x+2 x=1+2+x 0x=1+2 0x=3 0x=/=3 (=/= means does not equal) so there is no solution
0
This is always true! According to the Additive Inverse Axiom -X+X always equals 0 which is equivalent to 0X.
