Answer:

6x² - 19x + 10

Step-by-step explanation:

Given

(3x - 2)(2x - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(2x - 5) - 2(2x - 5) ← distribute both parenthesis

= 6x² - 15x - 4x + 10 ← collect like terms

= 6x² - 19x + 10

The equation x2 − 9 = 0 has real solution(s).
tatiyna

Answer:

The roots are real and unequal (3, -3)

Step-by-step explanation:

x²-9=0

ax²+bx+c=0

Comparing we get,

a= 1

b= 0

c = -9

Determinant: b²-4ac

= 0² - 4(1)(-9)

= 36>0

D > 0

Therefore, the equation has real and unequal roots.

Algebraic identity:

x² - a² = (x-a)(x+a)

Using this identity

x²-9 = (x+3)(x-3)

Roots are 3 and -3 which are real and not equal to each other

Hope this answer helps you ..

Does anyone know the answer to this question

ANSWER

\cos B = \frac{ \sqrt{3} }{3}

EXPLANATION

The given triangle is a right triangle.

It was given that,

a = 1

and

b =  \sqrt{2}

Using the Pythagoras Theorem, we can determine the value of c.

{c}^{2}  =  {( \sqrt{2} )}^{2}  +  {1}^{2}

{c}^{2} = 2 +  1

{c}^{2} = 3

c =  \sqrt{3}

The ratio is the adjacent over the hypotenuse.

\cos B =  \frac{1 }{ \sqrt{3} }

We rationalize to get:

\cos B =  \frac{ \sqrt{3}  }{ \sqrt{3}  \times  \sqrt{3} }  =  \frac{ \sqrt{3} }{3}
