Solve x²-x-30=0 using the factorisation method.​

Mathematics
1 answer:
Furkat [3]3 years ago
8 0

Answer:

Step-by-step explanation:

x²-x-30=0

x² - 6x + 5x - 30 = 0

(x² - 6x) + (5x - 30) = 0

x(x - 6) + 5(x - 6) = 0

(x + 5)(x - 6) = 0

x + 5 = 0 or x - 6 = 0

x = -5 or x = 6

The can of wood stain is twice as wide but half as tall as the can of paint. What is true about the areas of their labels?
MAXImum [283]
In this case the areas would be exactly the same. To prove this, think of a can of stain as 4 inches wide by 6 inches tall/long. If the can of paint is 8 inches wide and 3 inches tall/ long, both areas would be 24 inches squared. By cutting one dimension in half and doubling the other dimension, you do not change the overall area.
