Answer:
Option 1, 2, 5 are the correct answer.
Explanation:
We have the quadratic equation, 
First derivative of the equation is given by 2x - 6 = 0
So x = 3
At x = 3 the value of quadratic equation is extreme, corresponding y is given by 
, So extreme value is at (3,-7)
Second derivative of the quadratic equation is given by 2 ( positive value)
Second derivative is positive so graph of equation has a minimum value.
Now root of the equation is given by
or
Option 1, 2, 5 are the correct answer.
Answer:
Step-by-step explanation:
(2x + 1)(ax + b) = 6x² - 5x + c
Expand the left side and put that half into standard form:
2ax² + 2bx + ax + b = 6x² - 5x + c
2ax² + (2b + a)x + b = 6x² - 5x + c
So now look at the x terms. We have "2a" x² on left and 6 x² on right, so:
2a = 6
a = 3
Then look at the x terms, those coefficients will then be equal:
2b + a = -5
2b + 3 = -5
2b = -8
b = -4
and finally, then non-x terms are equal:
b = c
-4 = c
so:
a = 3, b = -4, c = -4
