Simplify<br>-6√20+2√45+7√5 <br><br>show Woking out to prove ans please

Dmitry_Shevchenko [17]

Answer:

$\sqrt{5}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{20}$ = $\sqrt{4(5)}$ = $\sqrt{4}$ × $\sqrt{5}$ = 2 $\sqrt{5}$

$\sqrt{45}$ = $\sqrt{9(5)}$ = $\sqrt{9}$ × $\sqrt{5}$ = 3 $\sqrt{5}$

Thus

- 6(2 $\sqrt{5}$ ) + 2(3 $\sqrt{5}$ ) + 7 $\sqrt{5}$

= - 12 $\sqrt{5}$ + 6 $\sqrt{5}$ + 7 $\sqrt{5}$

= $\sqrt{5}$

Use the discriminant to determine the number of real solutions of the equation.<br> x^2 = -6x - 10

HACTEHA [7]

Answer:

No real solutions.

Step-by-step explanation:

x² + 6x + 10 = 0

a = 1

b = 6

c = 10

D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4

- 4 < 0,

so this equation has no real solutions.
