Question

7. Find the quadratic polynomial whose roots are 2,-1?
8. Find the quotient and remainder when p(x) = x2-3x2+5x-3 is divided by g(x) = X-2?
9. Check weather t2-3 is a factor of 214+3t-2t2-9t-12 ?
10. Find the quadratic polynomial with zeros -2 and 1/3?
​

Answer 1

Answer:

quadratic polynomial whose roots are 2 & -1 is

(x+2)(x-1)= 0

x^2 + x -2 = 0

-2x + 1 is is quotient and -1 is remainder

t^2 - 2 is factor of given polynomial, is satisfy the equation

equation who's zeroes are -2 & 1/3 is

(x-2)(x+1/3)=0

x^2 -5/3x -2/3 =0

3x^2 -5x -2 = 0
