有咩功課唔識come in~~~

我都有野ng識ar~!

1.Solve 4x-20x+25=0
2.Solve(2x-3)-1=0
3.By using quadratic formula,solve x-2x-1=0 (to 2 d.p.)
4.If 4x+3x+k=0 has no real roots,find the range of k
5.If 2x+kx+(k-2)=0 has equal root,find the value of k
6.If the product of two consecutive even number 168,find the two numbers
7.(a)Solve x+x-12=0
7.(b)If the area of the triangle is 6cm,find the value of x

呢個都ng知岩ng岩ga...錯左ng好怪我....(你話1-3識...甘我ng打la...)

5.If 2x+kx+(k-2)=0 has equal root,find the value of k

2x+kx+(k-2)=0
3+ 1.5 k + k-2=0 (proved in (2))<..括號果d可以ng寫...
1-2.5k=0
2.5k = -1
k=-1/2.5
  =-0.4....

ng知岩ng岩ga

7(a)

x+x-12=0
2x-12=0
2x=12
x=6...
