What are the solutions of the equation?

yKpoI14uk [10]

Answer:

Option (b) is correct.

The solution of the quadratic equation $x^2+4x=21$ is -7 and 3

Step-by-step explanation:

Consider the given quadratic equation $x^2+4x=21$

This can be rewritten as, $x^2+4x-21=0$

We can solve the quadratic equation using middle term splitting method,

4x can be written as 7x-3x , we get,

$\Rightarrow x^2+4x-21=0$

$\Rightarrow x^2+7x-3x-21=0$

Taking terms common, we get,

$\Rightarrow x(x+7)-3(x+7)=0$

Thus, $\Rightarrow (x-3)(x+7)=0$

Thus, we get (x-3)= 0 or (x+7)= 0

this gives x = 3 or x = -7

Thus, the solution of the quadratic equation $x^2+4x=21$ is -7 and 3

Which of the following is a factor of 2x^3+13x^2+19x+20

zzz [600]

Answer:

$(x+5)$

Step-by-step explanation:

$2x^3+13x^2+19x+20$

$\frac{2x^3+13x^2+19x+20}{x+5}$

$2x^2+\frac{3x^2+19x+20}{x+5}$

$2x^2+3x+\frac{4x+20}{x+5}$

$2x^2+3x+4$

Now we got.

$\left(x+5\right)\left(2x^2+3x+4\right)$

$\left(x+5\right)$
