Question

6x2-30=0

It says find all the coefficients in the quadratic equation! It says find a, b, and c and I’m so confused please help me!

Answer 1

The quadratic form is ax^2 + bx + c

The given equation is 6x^2 -30 = 0

a = 6 because it is with x^2.

There is no x term in the equation so b is 0

c is the numerical term with no variable so c = -30

a = 6

b = 0

c =-30

Answer 2

Step-by-step explanation:

$6 {x}^{2} - 30 = 0 \\ \therefore \: 6( {x}^{2} - 5) = 0 \\ \therefore \: {x}^{2} - 5 = 0 \\ \therefore \: {x}^{2} = 5\\ \therefore \: x = \pm \: \sqrt{5}$
