f) (3a-4b)²

= 9a² + 16b² - 24ab

g) x (3x - 2) - (3x² - 5)

= 3x² - 2x - 3x² + 5

= 5 - 2x

3) a) 4x - 2(x+5) = 3

4x - 2x - 10 = 3

2x = 10 + 3

2x = 13

x = 13/2

b) 3p(p+2) = 0

3p² + 6p = 0

3p + 6 = 0

3p = -6

p = -6/3

p = -2

c) (x+1) (3x - 2) = 0

3x² - 2x + 3x - 2 = 0

3x² + x -2 = 0

d) 2y² + 29y - 15 = 0

2y² + 30y - y - 15 = 0

2y ( y+15) -1 (y+15) = 0

(2y-1) (y+15) = 0

a.4x-2(x+5)=3
4x-2x+10=3
2x+10=3
2x=3-10
2x=-7
x=-7/2
b.3p(p+2)=0
3p square+6p=0
3p square=-6p
p square=-6p/3p
p square=-2p
p=√-2p
c.4x square-2x +3x-2=0
4x square+x=0
4x square=-x
x =√-x/4
I think it's help you
