Question

Which of the following equations has roots 3,5 ? A) X 2 - 15X + 8 = 0. B) X2 - 8X + 15 = 0 C) x2 + 3 X + 5 = 0 D) 3x2 + 15x + 3 = 0​

Answer 1

Answer:

B) X2 - 8X + 15 = 0 is the answer..

Step-by-step explanation:

The roots of the quadratic equation x2 – 8x + 15 = 0 are

x2-5x-3x+15=0⇒x(x-5)-3(x-5)=0

⇒x(x-5)-3(x-5)=0⇒(x-3)(x-5)=0

⇒x=3,5
