Answer 1

Step-by-step explanation:

♠The general form of a quadratic function is f(x)=ax2+bx+c where a, b, and c are real numbers and a≠0.

♥The standard form of a quadratic function is f(x)=a(x−h)2+k.

♥The vertex (h,k) is located at h=–b2a,k=f(h)=f(−b2a).

Hope it helps...

Answer 2

Answer:

• When a polynomial f(x) is equated to zero , we get an equation which is known as a polynomial equation.

• If f(x) is a linear polynomial, then f (x) = 0 is called a linear equation.

For Example :- 4x - 2 = 0 etc.

• If (x) is a quadratic polynomial i.e, f(x) = ax² + bx + c , where a ≠ 0. Then f(x) = 0 i.e, ax² + bx + c = 0 , is called a quadratic equation.

★ General Form of quadratic equation ★

➤ The general form of a quadratic equation is ax² + bx + c = 0, where a, b , c are real numbers and a ≠ 0$.$
