Answer:
Roots are x=6 and - 4
Step-by-step explanation:
2(x-6)(x+4)=0
(x-6)=0 or (x+4)=0
x=6 or x=-4, their multiplicities is 1
Answer:
78
Step-by-step explanation:
= 12 x^2 - 30 put in ' - 3 ' for 'x'
= 12 ( -3 )^2 - 30
= 12 (9) - 30 = 78
Answer:
x=2
Step-by-step explanation:
-14x+28+6x=-44
-8x+28=-44
-8x= -16
x=2
