first factor out -4
-4(x^2 + 7x + 12)
then you can factor what is in parenthesis
-4(x+4)(x+3)
4/12 in simplest form is 1/3
4/12 ÷ 4/4 = 1/3
Answer:
x=-85
Step-by-step explanation:
x-18=-103
x=-103+18
x=-85
Answer:
The answer is 4
Step-by-step explanation: i did it
Answer:
D
Step-by-step explanation:
Given
9 - 7x = (4x - 3)² + 5 ← expand the squared factor
9 - 7x = 16x² - 24x + 9 + 5, that is
9 - 7x = 16x² - 24x + 14 ( subtract 9 - 7x from both sides )
0 = 16x² - 17x + 5, that is
16x² - 17x + 5 = 0 ← in standard form → D
