Select the correct expression which is used to write a quadratic equation when roots of a equation are given

x²-px+S=0

Sx²-px+c=0

x²-Sx+p=0

x²-sp+1=0

Equations having same solution are called:

Reciprocal equation

Simultaneous equation

Radical equation

exponential equation

Select the right option for 8x⁶ – 19x³ -27=0 to change it into quadratic equation

x³=y

x=y

x⁶=y²

x⁶=y

The extra solution of the equation is also called as

Square Roots

Cube roots

Extraneous Roots

Complex Roots

If S and P are sum and product of roots of an equation then the equation is:

x² – Sx -P = 0

x² – Sx +P =0

x² + Sx -P = 0

x² + Sx + P = 0

The solution which don’t satisfy the equation are called:

Extraneous roots

Roots

None of these
