give solutionnnnnn plzzzzz only question 15 ​

Answer 1

Heya mate..here is ur answer..

Answer 2

Answer:

Step-by-step explanation:

X - 2 = 0. , x-1/2 = 0

X = 2. , X = 1/2

We know when we put factors of X in eq, eq will be equals to 0

Px² + 5x + r

X = 2

P(2)² + 5×2 + r

4p + 10 + r = 0 ..........1

X = 1/2

P(1/2)² +5×1/2 + r = 0

P/4 + 5/2 + r = 0

On taking LCM

P + 10 + 4r ÷ 4 = 0

P + 10 + 4r = 0 ............2

Eq 1 nd 2 are equal

4p + 10 + r = p + 10 + 4r

10 get cancelled

4p + r = p + 4r

4p - p = 4r - r

3p = 3r

P = r

Hence proved
