Insert parentheses in Expression 2 so that it has a value of 19. Then show why your expression has a value of 19.
B) -74
C) 7
D) 9
If the quadratic equation x^2 + 18x +74=0 is rewritten in the form (x-p)²= Q. Then the value of Q is 7.
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
Given
The quadratic equation .
If the quadratic equation is rewritten in the form
Add and subtract 9² in the equation.
We know the formula
Then equation will be
Add 7 both the sides, then
Thus the value of Q is 7.
More about the quadraticequation link is given below.
Step-by-step explanation:
The given quadratic equation:
To find, the value of Q = ?
Adding both sides 81, we get
⇒ - 2(x)8 +
= 81 - 74
Using the algebraic identity,
⇒ is the form of
Here, P = 9 and Q = 7
Thus, the value of Q "option C) 7" is correct option.
