So we literally plug in the coefficients. Into this formula. So let's say we have 3x squared plus 6xMoreSo we literally plug in the coefficients. Into this formula. So let's say we have 3x squared plus 6x minus 1 now we're going to plug this into the formula.
The standard form of quadratic equation is ax2 + bx + c = 0, where 'a' is the leading coefficient and it is a non-zero real number. This equation is called 'quadratic' as its degree is 2 because 'quad' means 'square'.
Okay then let's write it down as 2 X 4 equals to 9 X square. Minus 4 or you can also write it as 2 XMoreOkay then let's write it down as 2 X 4 equals to 9 X square. Minus 4 or you can also write it as 2 X 2 X 4 minus 9 x squared. Plus 4 equals to 0. Now we have to substitute x squared equals to Y. So.
The equation is quadratic in form if the exponent on the leading term is double the exponent on the middle term. Substitute u for the variable portion of the middle term and rewrite the equation in the form au2+bu+c=0 .

Substitute the expression for y from the linear equation, into the quadratic equation. In other words, substitute mx + d for y in y = ax² + bx + c. Now, rewrite the new quadratic equation in the standard form.
This is an intermediate course in formal algebra for students without a strong background in algebra.
In other words, the quadratic formula is simply just ax^2+bx+c = 0 in terms of x. So the roots of ax^2+bx+c = 0 would just be the quadratic equation, which is: (-b+-√b^2-4ac) / 2a. Hope this helped!
A quadratic equation is a second order equation written as ax2+bx+c=0 where a, b, and c are coefficients of real numbers and a≠0.
The 3 Forms of Quadratic Equations Standard Form: y = a x 2 + b x + c y=ax^2+bx+c y=ax2+bx+c. Factored Form: y = a ( x − r 1 ) ( x − r 2 ) y=a(x-r_1)(x-r_2) y=a(x−r1)(x−r2) Vertex Form: y = a ( x − h ) 2 + k y=a(x-h)^2+k y=a(x−h)2+k.
