If α and β are the roots of 2x^2+x+3 = 0, find the quadratic equation whose roots are (α -1) and (β-1) About the author Ximena
Answer: thx for answering , mark brainliest Step-by-step explanation: please i cant type alpha and beta , so denoting them with p and q respt. for this quad eqn. a=2 , b=1 , c=3 (for an eqn in form of ax^2 +bx + c) p+q=-b/a = -1/2 pq=c/a = 3/2 now we need eqn. whose roots are x-1 and y-1 we can write it as x^2 – (p+q-1-1)x + (p-1)(q-1) x^2 + (-1/2 – 2)x + pq – p – q +1 x^2 + (-5/2)x + 3/2 -1(-1/2) +1 x^2 -5/2x + 3/2+1/2 +1 x^2 -5/2x + 6/2 x^2-5/2x + 3 = 2(x^2/2 – 5/2 + 3/2) hope it helps mark brainliest thanks Reply

Step-by-step explanation:
please i cant type alpha and beta , so denoting them with p and q respt.
for this quad eqn. a=2 , b=1 , c=3 (for an eqn in form of ax^2 +bx + c)
p+q=-b/a = -1/2
pq=c/a = 3/2
now we need eqn. whose roots are x-1 and y-1
we can write it as
x^2 – (p+q-1-1)x + (p-1)(q-1)
x^2 + (-1/2 – 2)x + pq – p – q +1
x^2 + (-5/2)x + 3/2 -1(-1/2) +1
x^2 -5/2x + 3/2+1/2 +1
x^2 -5/2x + 6/2
x^2-5/2x + 3
= 2(x^2/2 – 5/2 + 3/2)
hope it helps
