Question

2x$2x^{2} +11x+14$
solve this quadratic equation
if the equation is wrong let me know

Answer 1

Step-by-step explanation:

The question is not wrong but bit confusing.

$2 \times 2 {x}^{2} + 11x + 14 \\ = 4 {x}^{2} + 11x + 14$

is the quadratic equation.

D=b²-4ac

= (11)²-4(4)(14)

= 121-224

= -103

so D is in negative.

So no roots are possible

Answer 2

Answer:

$4{x}^2+11x+14$

so this is a quadratic equation.

to check the real roots .

Formula is = D = $b^{2}-4ac$

$4{x}^2 +11x +14$

putting the value in the formula .we get,

a =4

b =11

c =14

so,

$11^{2} -4(4×14)$

$121 - 4×56$

$121 - 224$

$-103$

D is a negative number and it's value is less than 1

here is no real roots.

but your equation is quadratic.
