after i do star method and i want to do (a+b)(a-b) how do i format it with 9^2/3 and 9^2/3

W²( 45W²+30W+5)

#

5W²(9W²+6W+1)

#

=》W²(3W+1)² thus repeated roots at 0 and -1/3

fierce shard i do star method after your step 2

I'm afraid I don't know what that is

#

Well there is the correct solution nonetheless

What do you think

#

I'm going to teach you a faster method

#

Consider the quadratic 9x²+6x+1

#

Multiply the co- efficient of x² to c

#

Giving us x²+6x+9

#

You'll see that x²+6x+9=(x+3)²

#

However

#

We must divide the three by the 9

#

(x+3/9)²=(x+1/3)²

#

The we just multiply by 3

#

(3X+1)²

#

Hope this helps 🙏
