Question

3x²+5x=0 find out using formula​

Answer 1

Answer:

x= 0 OR x = 5/3

Step-by-step explanation:

$3 {}^{2} + 5x + 0 = 0$

here, a=3; b=5; c=0

using quadratic formula,

(-b±√(b²-4ac))/(2a)

$- 5 + - \sqrt{(5 {}^{2} } - (4 \times 3 \times 0)) \div 2(3)$

$- 5 + - \sqrt(25 - 0)\ \div 6$

$( - 5 - + 5) \div 6$

$( - 5 + 5) \div 6 = 0$

OR

$( - 5 - 5 )\div 6 = 10 \div 6= 5 \div 3$

Thus x= 0 or x= 5/3
