Take x common

we get

x(3x^2 - 24x + 48)

x(3x^2 - 12x - 12x + 48)

x[3x(x-4) - 12(x-4)]

x(3x-12)(x-4)

FACTORS=>

x = 0

3x-12=0

=>3x=12

=>x=4

x-4=0

=>x=4

HOPE MY ANSWER WILL HELP YOU:)

ishaandagamer: Sorry, According to the given answers, it's incorrect. The textbook says 3x(4-x)^2. I'm just trying to understand how it got there

cooldab: LET ME CHECK

cooldab: IF we open the bracket in the answer it should match with the number which is not happening.Try opening it you will get 3(3x^3-48x)where did the 24x go

cooldab: once again check the answer

cooldab: it is which book tell me the name with the exercise number

ishaandagamer: Sorry, you're correct, i was looking at a different question

cooldab: It's Ok.Now are you clear
