Answer:

x = - 7, x = - 2

Step-by-step explanation:

Given

x² + 9x + 14 = 0

Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (+ 9)

The factors are + 7 and + 2, since

7 × 2 = 14 and 7 + 2 = 9, thus

(x + 7)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 2 = 0 ⇒ x = - 2

Answer:

$5^{9}$ can not be expressed as a square of any other number.

Step-by-step explanation:

The number 1953125 is equal to $5^{9}$ .

Now, the above statement gives an idea that 1953125 i.e. $5^{9}$ is not a square number as 9 is not a multiple of 2.

So, we can not express $5^{9}$ as a square of any other number.

We can only express $5^{9}$ as $(5^{4} )^{2} \times 5$ .
