Equation:
25z² + 25z - 3 = 0
Answer:
This quadratic equation can be solved by either factorization or by Sridharan's formula.
Formula:
x = [-b ± √(b²- 4ac)]/2a
Step-by-step explanation:-
Here b = 25 , a= 25 ,c = (-3)
substitution and simplification,
=> x = [-25 ± √(625 + 300)]/50
=> x = [-25± 5√13]/50
=> x = (-5±√13)/10
Since the given equation is quadratic it will be having 2 solutions for x,
they are
1). x = (-5 +√13)/10
and
2) x = (-5 - √13)/10

Answer:
The solution to this equation could not be determined.
Step-by-step explanation:
Simplifying
25z2 + 36 = 0
Reorder the terms:
36 + 25z2 = 0
Solving
36 + 25z2 = 0
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-36' to each side of the equation.
36 + -36 + 25z2 = 0 + -36
Combine like terms: 36 + -36 = 0
0 + 25z2 = 0 + -36
25z2 = 0 + -36
Combine like terms: 0 + -36 = -36
25z2 = -36
Divide each side by '25'.
z2 = -1.44
Simplifying
z2 = -1.44
Reorder the terms:
1.44 + z2 = -1.44 + 1.44
Combine like terms: -1.44 + 1.44 = 0.00
1.44 + z2 = 0.00
The solution to this equation could not be determined.
