Answer:
-9
Step-by-step explanation:
I believe B. is your answer. If you use the ac method, you will multiply 8 and 3 which is 24. So now, what factors of 24 will give you 10?6 and 4
Now substitute

Now do factorization by grouping.

Therefore, your answer is (4x+3)2x+1)
Answer:
{-12,0}
Step-by-step explanation:
first to solve this can collect like terms and add
X² +12x=0
and solve it by factorization method
X² +12x=0
x(x+12)=0
it means x multiplied by x = X² then x multiplied by 12 = 12x
so this means x or (x+12) equals to zero
x=0 and (x+12)=0
x+12=0
x=-12
so the solution set is {-12,0}
but can also be done by formula method
Answer:
step 3
Step-by-step explanation:
in step 3, he wrote that the sum of 171+ 52.45-18.50 was 241.95 when it is 199.95
