Question

write the following quadratic equations in its standard form & write the values of a,b,c. [(m×m)/5] -4=0​

Answer 1

Answer:

The Standard Form

We know that a quadratic polynomial can be written as ax2 + bx + c. If the quadratic polynomial = 0, it forms a quadratic equation. Therefore, the standard form of a quadratic equation can be written as: ax2 + bx + c = 0 ; where x is an unknown variable, and a, b, c are constants with ‘a’ ≠ 0 (if a = 0, then it becomes a linear equation). The constants ‘a’, ‘b’ and ‘c’ are called the coefficients. Let us look at some examples of a quadratic equation:

2x2+5x+3=0; In this, a=2, b=3 and c=5

x2-3x=0; Here, a=1 since it is 1 times x2, b=-3 and c=0, not shown as it is zero.
