Which of the following quadratic equations has roots 3 , 5 ? 1 point (C) x² - 8x +15 =0 (A) x² - 15x + 8 =0 (B) x² +8x -15 =0 (D) x² + 3x +5 = 0
Answered by admin @
Answer:
Answer is option C. -8x+15=0
Step-by-step explanation:
Here are the steps:
-8x+15=0
finding roots by factorizing:
-3x-5x+15=0
x(x-3)-5(x-3)=0
(x-5)(x-3)=0
therefore,
x-5=0 or x-3=0
x=+5 or x=+3
therefore the roots are 3 and 5.
