Answer:
the solution of given quadratic function is x = -2 and x=8
Step-by-step explanation:
Step:-1
Given quadratic function is [tex]-2 x^{2} +12 x+32=0[/tex]
Taking common '-2' term is
[tex]-2 (x^{2} -6 x+-16)=0[/tex]
dividing '-2' on both sides we get,
[tex]( x^{2} -6 x -16)=0[/tex]
Now finding factors 16 = 8 X 2
[tex]x^{2} - 8 x + 2 x - 16 =0[/tex]
[tex]x( x-8)+2(x-8) = 0[/tex]
[tex](x-8)(x+2)=0[/tex]
[tex]x - 8 = 0 and x+2 =0[/tex]
x = 8 and x=-2
Answer: the solutions are
x = 8
x = - 2
Step-by-step explanation:
The given quadratic function is expressed as
f(x) = -2x² + 12x + 32 = 0
Since 2 is a common factor of the function, we would divide through by 2, it becomes
- x² + 6x + 16 = 0
Next, we would find two numbers such that their sum or difference is 6x and their product is - 16x^2. The two numbers are 8x and -2x. Therefore,
- x² + 8x - 2x + 16 = 0
- x(x - 8) - 2(x - 8) = 0
(x - 8)(- x - 2) = 0
x - 8 = 0 or - x - 2 = 0
x = 8 or x = - 2
