Answer:
incorrect is They have a sum of -14
Answer:
-3
Step-by-step explanation:
-2(2x+5)-x=5(x+1) +15
distribute
-4x-10-x=5x+5+15
add common terms
-5x-10=5x+20
move common terms to the same sides
-30=10x
divide
x=-3
Because it’s important to know the equation so that would be easy to know the quadratic formula and easy to solve the problem
