Answer:
(x - 43)(x + 3)
Step-by-step explanation:
consider the factors of the constant term (- 129) which sum to give the coefficient of the x- term (- 40)
the factors are - 43 and + 3 , since
- 43 × + 3 = - 129 and - 43 + 3 = - 40 , then
x² - 40x - 129 = (x - 43)(x + 3) ← in factored form
Answer:
y=2x-1
Step-by-step explanation:
Answer:
The value of x for the given expression is 5 .
Step-by-step explanation:
Given expression as
+ =
Now, arrange the equation
So, = -
<u>Taking L.C.M on right hand side </u>
Or, =
Or, =
Or, x =
∴ x = 5
So, The value of x = 5
Hence,The value of x for the given expression is 5 . Answer
Answer:
Step-by-step explanation:
The given equation is :
We need to find the value of x.
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :
We know that, 4×4= 16 and 5×5 = 25
So,
So, the solution of the given equation is 4/5.
