Sqrt7x( sqrt x - 7 sqrt 7)
Andreyy89

Answer:

x\sqrt{7} - 49\sqrt{x}

Step-by-step explanation:

We have to simplify the following expression: \sqrt{7x}(\sqrt{x} - 7\sqrt{7})

Using distributive property:

\sqrt{7x}(\sqrt{x} - 7\sqrt{7}) = \sqrt{7x}\sqrt{x} - 7\sqrt{7}\sqrt{7x}

⇒ x\sqrt{7} - 49\sqrt{x}

So the most simplified form of the expression is the following: x\sqrt{7} - 49\sqrt{x}

What are the actual roots of 2x^2+2x-24
Reptile [31]

Answer:

The roots are 3 and -4

Step-by-step explanation:

Well the roots of a polynomial are when that polynomial is set to zero. So this becomes 2x^{2} +2x-24=0. Dividing by two on both sides we get x^{2}+x-12=0. Then, by factoring we get (x+4)(x-3)=0. Then, since one of them has to be zero, we get two equations: (x+4)=0 and (x-3)=0. Solving we get x=-4 and x=3.
