Question

Someone pls answer this

Answer 1

• 5 x² - 29 x + 20

   = 5 x² - 25 x - 4 x + 20

  = 5 x( x - 5 ) - 4 ( x - 5 )

  = (5 x - 4 )(x-5)

• x² - 2

      = 1(x² - 2)

• x² - 5 x

     = x ( x - 5 )

• x² - 9

    x² - 3²

    (x+3)( x-3)

Answer 2

1. 5x²-29x+20=0

==>5x²-25x-4x+20=0

==>5x(x-5)-4(x-5)=0

==>(5x-4)(x-5)=0

x=5

x=4/5

2. x²-2=0

==>x²=2

==>x=√2

or

==>x=-√2

3.x²-5x=0

==>x(x-5)=0

x=0

x=5

4.x²-9=0

=>x²=9

==>x=3

or

x=-3

Have a nice day
