@Jaxs

jhonyy9 · Answer

@mxddi3 so than you check this above wrote work by @Jaxs the half part is correct bc. 5*6 = 30

but you need get two numbers with sum -11 and product 30

mxddi3 · Answer

it'd be -6 and -5, right?

jhonyy9 · Answer

yes this is correct

jhonyy9 · Answer

so than how will be this equation factorized ?

mxddi3 · Answer

so you would have in parenthesis (x-5)(x-6)

and using what you showed me yesterday: 
|dw:1603907881157:dw|
and then (x-5)(x-6) written out is 
x^2-11x+30
