alright

#

you know how to factor a quadratic right? multiply the coefficient of x^2 and the constant term and split the middle term in such a way

prime peak
#

Noo I dont know it new topic

#

granite thunder
#

#

alright so you know how to multiply two binomials?

#

like (x+a)(x+b)

prime peak
#

granite thunder
#

#

lets trys using it on (x+a)(x+b)

#

x^2+ax+bx+ab

prime peak
#

Yess

granite thunder
#

basically

#

when we factor

#

we want to split the middle term

#

in such a way that we get something common

#

let me share it with an example

prime peak
#

Okieee :)

granite thunder
#

$x^2+2x+1$

$x^2+x+x+1$

$x(x+1)+1(x+1)$

$(x+1)(x+1)$

#
