3x2 - x - 102 = 0Factor the left side:(3x + 17) times (x - 6) = 0The two solutions are:3x + 17 = 03x = -17x = -17/3andx - 6 = 0x = 6
x - 6x = 0-5x= 0x = 0/-5which equals x = 0
y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
x + 4x = 05x = 0x = 0/5x = 0
sqrt( 3x + 4 ) = 23x + 4 = 43x = 0x = 0Marvelous.
x2 - 5x = 0x (x - 5) = 0x = 0andx = 5
This is always true! According to the Additive Inverse Axiom -X+X always equals 0 which is equivalent to 0X.
x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8
Multiplication Property of Zero
x2 - 5x = 0Factor the left side:x (x - 5) = 0x = 0x = 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 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
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
x+1=x+2 x=1+2+x 0x=1+2 0x=3 0x=/=3 (=/= means does not equal) so there is no solution
3x2 - x - 102 = 0Factor the left side:(3x + 17) times (x - 6) = 0The two solutions are:3x + 17 = 03x = -17x = -17/3andx - 6 = 0x = 6
x - 6x = 0-5x= 0x = 0/-5which equals x = 0
f'(x)= 0x^-1=0anything multiplied by zero equals zero
