Hey there!!
Given equation :
f ( x ) = x² + 2x + 1
Find f ( 2b )
In order to solve this question, we will need to replace the value 2b instead of x
... f(2b) = ( 2b )² + 2 ( 2b ) + 1
... f(2b)= 8b² + 4b + 1
Hope my answer helps!
Step 1) Add x to both sides and simplify
1+4x=4
Step 2) Subtract 1 from both sides
4x=3
Step 3) Divide everything by 4
x=4/3 (1 1/3) (1.333)
Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
