The polynomial is:
12 x³ - 6 x² + 8 x - 4
Lucas:
( 12 x³ + 8 x ) + ( - 6 x² - 4 ) = 4 x ( 3 x² + 2 ) - 2 ( 3 x² + 2 ) =
= ( 3 x² + 2 ) ( 4 x - 2 ) = 2 ( 3 x² + 2 ) ( 2 x - 1 )
Erick:
( 12 x³ - 6 x² ) + ( 8 x - 4 ) = 6 x² ( 2 x - 1 ) + 4 ( 2 x - 1 ) =
= ( 2 x - 1 ) ( 6 x² + 4 ) = 2 ( 3 x² + 2 ) ( 2 x - 1 )
Answer:
Both students are correct. Each grouping leads to the same result.
it's B! because it's what was already given to you next to the picture, and it just wanted you to rewrite it into the proof
So,
"89 more than" = 89 +
"the quotient of an unknown number and 62" = 62 over x
"is 94" = 94
Multiply both sides by x.
89x + 62 = 94x
Subtract 89x from both sides.
62 = 5x
Divide both sides by 5.
= x
Simplify.
