Explanation:
The standard form refers to the format of an expression where the terms are arranged in a descending order. The degree is determined by the exponent value of the variable of each term.
To find the standard form, multiply the brackets out and simplify.
y=(9x-2)(x+2)(7x-4)
Lets multiply out y=(9x-2)(x+2) first:
y=(9x-2)(x+2)
y=9x2+18x2x2
y=9x216x2
Then multiply y=(9x216x2)(7x4):
y=(9x216x2)(7x4)
y=63x336x2112x2+64x14x+8
y=63x3148x2+50x+8
This is the standard form.
