and yo ufind the x values

Answer 3

x intercepts

Answer 4

Step by step solution :

Step 1 :

Raise x to the 2nd power
Exponentiaion :

Equation at the end of step 1 :

(x2 - 15x) - 54
Step 2 :

Simplify x2-15x - 54
Trying to factor by splitting the middle term

2.1 Factoring x2-15x-54

The first term is, x2 its coefficient is 1 .
The middle term is, -15x its coefficient is -15 .
The last term, "the constant", is -54

Step-1 : Multiply the coefficient of the first term by the constant 1 • -54 = -54

Step-2 : Find two factors of -54 whose sum equals the coefficient of the middle term, which is -15 .

-54 + 1 = -53
-27 + 2 = -25
-18 + 3 = -15 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 3
x2 - 18x + 3x - 54

Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-18)
Add up the last 2 terms, pulling out common factors :
3 • (x-18)
Step-5 : Add up the four terms of step 4 :
(x+3) • (x-18)
Which is the desired factorization

Final result :

(x + 3) • (x - 18)
