Answer:

x= -2-√11. or. x= -2 + √11

Step-by-step explanation:

solving quadratic equation by completing the square

x^2+4x-7=0

x^2+4x=7

x^2+4x + (4/2)^2=7 + (4/2)^2 ( adding (1/2 coefficient of x)^2 on both sides

x^2+4x + 4=7 + 4

x^2+4x + 4=11. factorize(x^2+4x + 4) into (x + 2)^2

(x + 2)^2=11

√(x + 2)^2= + - √11

x + 2 = + - √11

there are two different solution .

x + 2 = -√11. or x + 2 = + √11.

x= -2-√11. or. x= -2 + √11.

The simplest form of the given expression 3\frac{11}{12} - 1\frac{4}{12} is \frac{31}{12}

<u>Solution:</u>

Given, expression is 3 11/12 – 1 4/12 \rightarrow 3 \frac{11}{12}-1 \frac{4}{12}

We have to find the simplest form of the value derived from the given expression.

Now, first let us solve the given equation.

3 \frac{11}{12}-1 \frac{4}{12}

converting mixed fractions to improper fractions.

=\frac{3 \times 12+11}{12}-\frac{1 \times 12+4}{12}

\frac{36+11}{12}-\frac{12+4}{12}=\frac{47}{12}-\frac{16}{12}=\frac{47-16}{12}=\frac{31}{12}

As there are no common terms to cancel it is in lowest form.

Hence, the lowest form of the given expression is \frac{31}{12}
