**Important Formulas| RD Sharma Class 10 Chapter-2**

Chapter-2 ‘Polynomials’ require you to have an understanding of the following formulas.

1. For a quadratic equation ax^{2} + bx + c, if you are given ɑ and 𝛃 as zeroes of the polynomial, then

ɑ + 𝛃 = - b/a

ɑ𝛃 = c/a

2. For a cubic polynomial ax^{3} + bx^{2} + cx + d, if you are given ɑ, 𝛃 and 𝛄 as zeroes of the polynomial, then

ɑ + 𝛃 + 𝛄 = - b/a

ɑ𝛃 + 𝛃𝛄 + 𝛄ɑ = c/a

ɑ𝛃𝛄 = -d/a

3. Division algorithm: When you divide a given polynomial p(x) with a non-zero polynomial g(x), then the quotient polynomial q(x) and remainder polynomial r(x) can be represented as follows.

p(x) = g(x) q(x) + r(x), where r(x) = 0 or degree of g(x) > r(x)
