(x-7)(x-5)=x-7
(x-7)(x-5)-(x-7)=0
(x-7)[(x-5)-1]=0
(x-7)(x-6)=0
x=7 or x=6
Hope this can help.
Good morning,
Answer:

Answer:
Step-by-step explanation:
-2x2-12x-15
Final result :
-2x2 - 12x - 15
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((0 - 2x2) - 12x) - 15
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-2x2 - 12x - 15 = -1 • (2x2 + 12x + 15)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 + 12x + 15
