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.
Answer:
7•3 = 21
Step-by-step explanation:
Improper Fraction: 21/4
Simple Fraction: 5 1/4
Answer:
x = 71
Step-by-step explanation:
<B is a right angle, so triangle ABE is a right triangle, and angles BAE and AEB are complementary.
m<BAE + m<BEA = 90
42 + m<BEA = 90
m<BEA = 48
<BEC is a straight angle, so its measure is 180 deg.
m<CED + m<DEA + BEA = 180
61 + x + 48 = 180
x + 109 = 180
x = 71
A because x intercepts at about-2 and y at 1.6
