Step-by-step explanation:
first you take out 4 leavinf you with 2x-1 and thennyou are done
8x - 4 is an expression. This means that x can mean anything.
If you mean 8*-4, the answer would be -32 because 8 multiplied by 4 is 32, but since a positive multiplied by a negative equals a negative, the product would become a negative.
Answer:
Is this a multiple choice?
28/3
2x²+5x-9=0
using quadratic formula
a=2 b=5 c=-9
x=[-5±√5²-4(2)(-9)]/2(2)
x=[-5±√97]/4
the zeros are( -5±√97)/4
