Question

for what values of x is the expression 2x^2+9x+10 positive
​

Answer 1

Step-by-step explanation:

2x²+9x+10

= 2x²+4x+5x+10

= 2x ( x+2 )+5 ( x+2 )

= ( 2x+5 )( x+2 )

now put both factor = 0

2x+5 = 0

x = -5/2 ( one value of x)

and

x+2 = 0

x = -2 ( second value of x)

this isa quadratic equation so it has two values of x,

thanks!
