Answer:

Step-by-step explanation:

13) x⁴-12x² +36    

(a-b)² = a²-2ab+b²

a = x² ; b = 6

(x²)² - 2 * x² * 6 + 6² =  (x² - 6)²

14) w⁴- 14w² - 32 =     w⁴+ 2w² - 16w² - 32  = w² (w² + 2) - 16 (w²+2)

                           = (w² + 2) (w² -16 )

15) k³ + 7k² - 44k = k ( k² + 7k -44)  = k ( k+11 ) ( k-4 )

16) 2a³ +28a²+96a =2a(a²+14a+48) = 2a(a+6)(a+8)

17) -x³ +4x² +21x = (-x) ( x² - 4x - 21) = (-x)(x-7)(x+3)

18) m⁶ - 7m⁴ -18m² = m² ( m⁴-7m²-18) = m² (m²-9)(m²+9)

                             = m² (m+1) (m-1)(m²+9)

19) 9y⁶ +6y⁴ + y²= y² ( 9y⁴+6y²+1) = y² (3y²+1)²

20) 8c⁴+10c² -3 = (4c +1)(2c-3)

K over x = w over v solve for x
Amiraneli [1.4K]
\frac{k}{x} = \frac{w}{v} Multiply both sides by v
<span>\frac{kv}{x} = w   Multiply both sides by x
</span>kv = wx   Divide both sides by w
<span>\frac{kv}{w} = x   Switch the sides to make it easier to read
</span>x = <span>\frac{kv}{w} </span>
