Question

a) x2 - 4x + 9 = 0
C) 2x2 - 10x = 0
b) x2 - 10x - 2 = 0
f) 3x2 - 27 = 0
c) 2x2 - 11x = 0
g) x2 - 10x + 16 = 0​

Answer 1

A) - 8x +9 = 0

-8x= -9

x= -9/8

x= -1,1

C) 4x - 10x =0

6x= 0

b) -8x - 2= 0

-8x= 2

x= 2/8

x= 0,2

f) 6x - 27= 0

6x= 27

x= 27/6

x= 4,5

c) 4x - 11x = 0

-7x = 0

g) -8x +16= 0

-8x = -16

x= -16/8

x= - 2
