What are the roots of the polynomial equation?<br><br> x2−14x−32=0
Dmitry [639]

We are given the quadratic equation :

x^{2} -14x-32=0

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.

x^{2} -16x +2x -32 =0

Step 4:

Factoring by grouping.

x(x-16) +2(x -16) =0

(x-16) (x+2) =0

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.

In a video game, Bob can score 3 points (x) or 4 points (y) by hitting targets. To win the game he must score at least 20 points
MariettaO [177]
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

hope this helps
