What is the standard form of # y=(3x + 1)(x + 8) #?

Answer 1

#y = 3x^2 + 25x +8#

Expand the expression and then ensure the terms are in order of descending powers. #y = (3x^2 +x + 24x +8)# #y = 3x^2 + 25x +8#

To find the standard form of ( y = (3x + 1)(x + 8) ), you need to expand the expression using the distributive property and then simplify it.

( y = (3x + 1)(x + 8) ) ( = 3x \cdot x + 3x \cdot 8 + 1 \cdot x + 1 \cdot 8 ) ( = 3x^2 + 24x + x + 8 ) ( = 3x^2 + 25x + 8 )

Therefore, the standard form of the given expression is ( y = 3x^2 + 25x + 8 ).
