Question

How many solutions does 3x^2+11x+10=0 have

Answer 1

Answer:

Step-by-step explanation:

Let's find the discriminant $\Big(\sqrt{b^2-4ac}\Big)$

$\sqrt{11^2-4(3)(10)} = 1$

It is a positive number, therefore there are 2 solutions

Answer 2

Answer:

2 solutions

Step-by-step explanation:

3x^2+6x+5x+10=0

(3x)x(x+2)+5(x+2)=0

(x+2)x(3x+5)=0

x+2=0

3x+5=0

x=-2

x=-5/3
