Formula
(82-67)÷67×100=Answer
We are given the quadratic equation :
Now let us use AC method to factorise it.
Step 1:
Find product of A and C
A=1 and C =-32
A*C =-32
Step 2:
Find factors of -32 such that they add up to give -14.
Factors of -32 that add up to give -14 are -16 and 2.
Step 3:
Rewrite the equation using factors found in step 2.
Step 4:
Factoring by grouping.
Step 5:
Find roots.
x-16=0 gives x=16
x+2=0 gives x=-2
Answer : Roots of the given Polynomial equation are 16 and -2.
A parallel line should have the same slope so it'll have 3x and then you would just have to plug in your point and you'd eventually get b=1 so the answer is y=3x+1
Answer:
Step-by-step explanation:
The 12th term is gotten by replacing ń in the equation with 12. Hence,
a(12)= - 5+6(12-1)
Solving the bracket first by BODMAS,
a12= - 5+6(11)
Opening the bracket,
a12=-5+66
a12=66-5
a12=61
