Question

4-x2=5x standard form and values of a b c​

Answer 1

Answer:a=-1, b=-5, c=4

Step-by-step explanation:

The quadratic formula is ax^2+bx+c=0

So comparing this eq. From 4-x^2=5x

So , -x^2-5x+4=0

Therefore a=-1 , b= -5, c=4

Answer 2

Given,

The equation given here is $\[4 - {x^2} = 5x.\]$

To find,

The term a, b and c.

Solution,

Know that the standard form of an equation is given as $\[a{x^2} + bx + c = 0.\]$

Standardize the given equation.

$\[\begin{array}{l} \Rightarrow 4 - {x^2} = 5x\\ \Rightarrow {x^2} + 5x - 4 = 0\end{array}\]$

Compare the given equation with the standard equation.

$\[\begin{array}{l} \Rightarrow a = 1\\ \Rightarrow b = 5\\ \Rightarrow c = - 4\end{array}\]$

Hence, the value of a,b and c are $\[4,5\,{\rm{and}}\, - 4\]$ respectively.
