What is the standard form of # y= -9(x-1)(2x-4)(3x-1)#?

Answer 1

Hazel Anglin

the standard form of expression is #y=ax^3+bx^2+cx+d#

As the highest power in the algebraic expression

#−9(x−1)(2x−4)(3x−1)# is #x^3#, the standard form of this is

#y=ax^3+bx^2+cx+d#

Actual expansion of te expression gives us

#y=-54x^3+180x^2-162x+36#
