Question

if A and B are the zeros of the polynomial 2x square minus x minus 3 then write the polynomial whose zeros are a square, b square. ( 4 square - 13x +9)​

Answer 1

Answer:

• 2x2-x-3
• let p(x)=0
• 2x2-x-3=0
• 2*-3= -6
• 2x2+2x-3x-3=0
• (2x2+2x)+(-3x-3)=0
• 2x(x+1)-3(x+1)=0
• 2x-3=0. x+1=0
• 2x=3. x=-1
• x=3/2(or)-1
• (3/2)2=9/4
• (-1)2=1
• k(x2-x(a+b)+ab)
• k(x2-x(9/4+1)+9/4(1))
• k(x2-x(13/4)+9/4)
• k(4x2-13x+9/5)
• let k= 4
• 4x2-13x+9
