Question

Write the following quadratic equations standard form & find value of a, b & c
i) x²-3 = X
ii) 2x²-5x+7=0​

Answer 1

Answer:

X²-X-3=0 (1)

a=1,b=-1,c=-3

2X²-5X+7=0

a=2,b=-5,c=7

a is constant for term having variable of power 2

b is constant for term having variable of power 1

c is constant no variable

Answer 2

$\sf{Answer:}$

Standard forms :

(i) ${x }^{2} - x - 3 = 0$

Values of a, b and c are,

a = 1, b = -1, c = -3

(ii) $2 {x}^{2} - 5x + 7 = 0$

Values of a, b and c are,

a = 2, b = -5, c = 7

Standard form of a quadratic equation :

The standard form of a quadratic equation is said to be

$\boxed{a {x}^{2} + bx + c = 0}$
