My teachers taught me a trick make a C from the top to bottom
so 5 1/2 would be
5 times 1 + 2 so denominator stays the same so it 7/2.
bottom one is 22/4
make a C from top to bottom and multiply outer number to top add the bottom to that then keep denominator the same.
Hope i helped.
This is a polynomial with more than 2 as a degree. Using Descartes Rule of Signs:
f(x) = x⁶ + x⁵ + x⁴ + 4x³ − 12x² + 12
Signs: + + + + − + 2 sign changes ----> 2 or 0 positive roots
f(−x) = (−x)⁶ + (−x)⁵ + (−x)⁴ + 4(−x)³ − 12(−x)² + 12 f(−x) = x⁶ − x⁵ + x⁴ − 4x³ − 12x² + 12
Signs: + − + − − + 4 sign changes ----> 4 or 2 or 0 negative roots
Complex roots = 0, 2, 4, or 6
Answer:
Well
1) -2+(-7)
2) -7-2
Step-by-step explanation:
Both equations work and their equivalent
Break the shape into smaller rectangles and solve for there areas. Then add the areas together to get the total area of the figure. See the picture below where I solved the problem
Answer:
Step-by-step explanation:
3( 2x-4)=4(3/2x-3)
Opening bracket
6x - 12 = 6x - 12
6x - 6x = -12 + 12
No solution
