Answer:

4\sqrt{5}

Step-by-step explanation:

We are asked to write \sqrt{80} in the simplest form.

We can write 80 as product of 16 and 5.  

\sqrt{80}=\sqrt{16\cdot 5}

Using radical rule \sqrt{m\cdot n}=\sqrt{m}\cdot \sqrt{n}, we will get:

\sqrt{16\cdot 5}=\sqrt{16}\cdot \sqrt{5}

\sqrt{16\cdot 5}=\sqrt{4^2}\cdot \sqrt{5}

\sqrt{16\cdot 5}=4\sqrt{5}

Therefore, the simplest form of the given expression would be 4\sqrt{5}.

Find b and then solve the equation: 2x^2+bx−10=0, if one of its roots is 5
slavikrds [6]

Vietas formula tells us that the product of our two roots is equal to the constant term of a quadratic over the leading coefficient, so:

[tex] r_1r_2=-\frac{-10}{2} \implies 5*r_1=-5 \implies r_1=-1[\tex]

It also tells us that the b term in our quadratic is equal to the negative of the sum of the terms divided by the leading coefficient, so:

[tex] r_1+r_2=-\frac{b}{2} \implies 4=-\frac{b}{2} \implies b=-8 [\tex]

So, one of our roots is 5, the other is -1, and our b value is 8.

(Tough day dividing polynomials and I'm still lost!) Please help me my hands are legit numb:)
N76 [4]

Answer:

Option D. 9

Step-by-step explanation:

There are two ways to obtain the answer to the question.

Method 1:

Let 2x + 1 = 0

Making x the subject, we have

2x + 1 = 0

Collect like terms

2x = –1

Divide both side by 2

x = –1/2

Now, put the value of x into the expression 4x³ – 6x² – 8x + 7, we have:

4x³ – 6x² – 8x + 7

x = –1/2

4(–1/2)³ – 6(–1/2)² – 8(–1/2) + 7

4(–1/8) – 6(1/4) – 8(–1/2) + 7

–1/2 – 3/2 + 4 +7

– 4/2 + 4 + 7

– 2 + 4 + 7

= 9

Method 2:

Divide 4x³ – 6x² – 8x + 7 by 2x + 1
