Step-by-step explanation:
Quadratic Equation given:
In order to get rid of the fractions, multiply both sides by 4.
We get:
Completing the square:
Step-by-step explanation:
if x-4 is a factor of 2x^3 + x^2- 26x - 40
then f(4) = 0
f(x) = 2x^3 + x^2- 26x - 40
f(4) = 2(4)^3 + (4)^2 - 26(4) - 40
f(4)= 2(64) + 16 - 104 - 40
f(4) = 128 + 16 - 104 - 40
f(4) = 0
hence factorize completely is the photo
Answer:
70 degrees
Step-by-step explanation:
Find the diagram attached
The sum of the angles is supplementary that is
45 + 2x- 5 = 180
2x + 40 = 180
2x = 180 - 40
2x = 140
x = 140/2
x = 70
Hence the value of x is 70 degrees
