Question

solve question number 3..​

Answer 1

Answer:

a=b=1

EXPLANATION

the equation of the form ax³ + bx² + cx + d

we can write,

sum of the roots = -b/a

and product of the roots = -d/a

using this we can solve to get

sum of the roots =

a + b + a + a - b =- (- 3)

3a = 3            and a = 1

NOW product of the roots =

( a+b)(a)(a-b) = -1

(a²-b²)(a) = -1

putting a = 1

we get       -b²= -1

thus b = 1
