a) Tyler made an error in his factorization. U can only factorize an equation, and this happens to be an expression, not an equation
6 -2x +5 +4x is not the same as (6 -2)x + (5 +4)x
-2x +4x +5 +6=0
+2x +11 =0
2x =-11
2x÷2 = -11÷2
x= -5.5
Answer:
a. The error he made was not simplifying properly by adding like terms.
b. 11 + 2x
Explanation:
6 - 2x + 5 + 4x
Step 1. Add like terms. 6 and 5 are like terms. -2x and 4x are like terms.
6 + 5 = 11
-2x + 4x = 2x
11 + 2x
