Amaths Homework,ex 3B.

hyeee people~

well,just to remind you guys bout our Amaths homework.hihi =)
anyway,the exercises I'm going to write below is dedicated to Nowre because her textbook is not with her,and so here it is.Finish this exercise,Nowre!
I'm trying to help you =)

EXERCISE 3B

1.Solve the following equations by factorisation:

(a) X2 + 3X = 10
(b) 2X = 6 - 11X
(c) (2X - 1) (X - 3) = 18
(d) (3X + 10) (X - 1) = 20X

2.Solve the following equations by completing square:

(b) X2 - 5X + 2 = 0
(d) 2X (1 - 2X) + 5 = 0

3.Solve the following equations by formula:

(b) 3X2 = X + 3
(d) (X - 1) (X - 3) = 2X + 5

5.Find the values of p if the following equations have equal real roots:

(b) X2 - 2px + p + 2 = 0
(d) X2 - 2x + 1 = p (X - 3)

7.Find the range of values of k for which the following equations have no real roots:

(b) 2X2 - 4X + k + 3 = 0
(d) 2X2 - 5X = kX2 + X - 3

DONE! hehee :)
so Nowre,if anything you're not so clear bout the questions,Just ask me :)
But,don't ask for the answers.HEHE
