(X+7)(X+1)
X=-1,-7
Answer:
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
(4x - 11i)(4x -+11i)
Step-by-step explanation:
Factor as a difference of squares
a² - b² = (a - b)(a + b)
note that i² = - 1
Given
16x² + 121
= (4x)² - (11i)²
= (4x - 11i)(4x + 11i)
8 - 1 = 7
7 - 9 = -2
7 divided by -2 is -3.5
The slope is -3.5 now we need to find the y intercept.
To find the y intercept do -3.5 times 7 and you get -24.5.
Next do 8- -24.5 and you get 32.5 which is the y intercept.
The equation would be y = -3.5x + 32.5
