Solutions are 3 and - 5.

Step-by-step explanation:

Step 1:

Given equation is 3x² + 6x = 45. Factorize the equation to get the solutions.

⇒ 3x² + 6x - 45 = 0

⇒ x² + 2x - 15 = 0

⇒ x² + 5x - 3x - 15 = 0 (Product and Sum Method where product of coefficients = - 15 and sum = 2)

⇒ x (x + 5) - 3(x + 5) = 0

⇒ (x - 3)(x + 5) = 0

⇒ x = 3, - 5

How can you find approximations of square roots?​
dem82 [27]

Step-by-step explanation:The second way of approximating a square root is to use a calculator. Most calculators have a radical sign on them. To find the square root of a number, we enter the radical sign, then the value and press enter. This will give us a decimal approximation of the square root.
