Find the square root of 3.6 upto 2 decimal places. *With Solution I need*
almond37 [142]

Answer:

The square root is 1.90

Step-by-step explanation:

Given

x = \sqrt{3.6}

Required

Find x

Express 3.6 as 36/10

So, we have:

x = \frac{\sqrt{36}}{\sqrt{10}}

This gives

x = \frac{6}{\sqrt{10}}

Rationalize

x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}

x = \frac{6\sqrt{10}}{10}

Using a calculator

\sqrt{10} \approx 3.16

So, we have:

x = \frac{6*3.16}{10}

x = \frac{18.96}{10}

x = 1.896

Approximate

x = 1.90

Solve 2x^2=11x+6 by factoring
Ede4ka [16]

Answer:

(x-6) (2x+1)

Step-by-step explanation:

1) move everything over to the left side, so subtract 11x and 6.

2x^2 -11x - 6 = 0

2)multiply 2(a term) with -6 (c term)

x^2 -11x -12

3) factor and find what multiples to -12 and adds up to -11. in this case its -12 and positive 1

(x-12) (x+1)

4) divide -12 and 1 by the original a term (2)

(x-6) (x+1/2)

5) move the denominator of 2 over to the x.

(x-6) (2x+1)
