Help with math please! 4x^2+12x+5 how would i do this equation?

Question

terenzreignz · Answer

Not an 'equation' unless there's an equals-sign.
Is it equal to zero?

Regardless, you might have to try and factor it anyway...

Sorry i need to factor it

anonymous · Answer

Here, we can use factoring decomposition; determine two values in which the product is 20 and the sum is 12. They are 2 and 10, so split 12x into 2x and 12x! 

4x² + 2x + 10x + 5 = 0 

Factor like terms.. 

2x(2x + 1) + 5(2x + 1) = 0 

Group the common factors of 2x + 1 and collect the terms.. 

(2x + 1)(2x + 5) = 0 

Finally, by zero-product property: 

2x + 1 = 0 and 2x + 5 = 0 
2x = -1 and 2x = -5 
x = {-½, -5/2}

Must defer.
I'm admittedly not good at teaching how to factor, it just happens... T.T

Also 16x^2-16x-12

read about quadratic equations.. solve it by discriminant... u will find dat it has no real solution.. not every quadratic has real solution
