Answer:
13x + x^2 - 9
Step-by-step explanation:
You have to distribute then eliminate redundant parentheses then subtract the numbers then combine like terms then multiply by one then combine like terms and then the answer is 1 13x + x^2 - 9.
Answer:
27
Step-by-step explanation:
We first subtract 44 from both sides so that the equation becomes -13x^2 + 17x - 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -17 ± √(17^2 - 4(-13)(-5)) ] / ( 2(-13) )
x = [ -17 ± √(289 - (260) ) ] / ( -26 )
x = [ -17 ± √(29) ] / ( -26)
x = [ -17 ± sqrt(29) ] / ( -26 )
x = 17/26 ± -sqrt(29)/26
The answers are 17/26 + sqrt(29)/26 and 17/26 - sqrt(29)/26.
Answer:
C and E
Step-by-step explanation:
Factor it so you get
(x-2)(x+5)=0
Then find x
x=-5
x=2
