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.
Well,
we know that we need to accumulate points from x and y to reach 20 points.
since x provide 3 and y provide 4 points, the formula would be :
3x + 4y = 20
or it can be written as :
y = (3x/4)+5

Answer:
x = -9
Step-by-step explanation:
4x+10=-26
Subtract 10 from each side
4x+10-10=-26-10
4x = -36
Divide each side by 4
4x/4 = -36/4
x = -9
Answer:
21/2 or 10.5
