Answer:
z = -1
Step-by-step explanation:
0 = 8z + 8
-8 = 8z
-8/8 = z
z = -1
check:
0 = 8*-1 + 8
0 = -8 + 8
So you multiply 3 on both sides to cancel out the denominator. which gives you 2a=24+12a. Subtract 12a on both sides. -10a=24 which is a=-2.4
Answer:
Hello :
4x² - 8x +3 = 0
4 ( x² - 2x +3/4 ) = 0
4 ( (x² -2x +1) -1 + 3/4) = 0
4 ((x-1)² - 1/4 ) =0
(x-1)² - 1/4 = 0
(x-1)² - ( 1/2 )²=0
( x - 1 -1/2 ) ( x - 1 +1/2 ) = 0
( x - 3/2) ( x - 1/2) = 0
x - 3/2 = 0 or x - 1/2 = 0
two solutions : 3/2 ; 1/2
