Question

i) Write the following quadratic equation in
standard form and write the values of a, b,c. x²-9=13x​

Answer 1

Answer:

we know the standard form of quadratic equation

ax2 + bx + c =0

so ,x2 -9 =13x

x2 - 13x - 9 = 0

I hope it also help for you

Answer 2

Answer:

The standard form of x²-9=13x​ is  $x^2-13x-9 = 0$ , and the values of a, b, c are 1, -13, -9 respectively.

Step-by-step explanation:

Given,

The quadratic equation x²-9=13x

The standard form of the quadratic equation is:

$ax^2+bx+c = 0$.....(1)

Now we can write the given quadratic equation as:

$x^2-13x-9 = 0$  (i.e. by bringing 13x from R.H.S to L.H.S)....(2)

Now by comparing equation (2) with equation (1)

we get:

a = 1, b = -13, c = -9.

Therefore, the standard form of x²-9=13x​ is  $x^2-13x-9 = 0$ , and the values of a, b, c are 1, -13, -9 respectively.
