When (2x-3)^2-3 is subtracted from 5x^2 the result is?

Answers

Answer 1

Answer: (2x-3)² - 3 is subtracted from 5x²

Solve the terms within the parenthesis and has exponents. Group like terms and simplify.

(2x-3)(2x-3) ⇒ 2x(2x-3) -3(2x-3) ⇒ 4x² - 6x - 6x² + 9 ⇒ -2x² - 6x + 9

Deduct 3 from the answer of the previous solution.
-2x² - 6x + 9 - 3 ⇒ -2x² - 6x + 6

Deduct the answer of the previous solution from 5x²

5x² - 2x² - 6x + 6 ⇒ 3x² - 6x + 6

3x² - 6x + 6 can be factored by 3.

3(x² - 2x + 2)

A = ¹/₂bh
A = ¹/₂(4z² - 10)(8z)
A = ¹/₂[4z²(8z) - 10(8z)]
A = ¹/₂(32z³ - 80z)
A = ¹/₂(32z³) - ¹/₂(80z)
A = 16z³ - 40z

tan ⊖ + cot ⊖ = 1/sin⊖cos⊖

Answers

tan ⊖ + cot ⊖ = 1/sin⊖cos⊖

sin ⊖ / cos ⊖ + cos ⊖/sin ⊖ = 1/sin⊖cos⊖

(sin ⊖*sin ⊖ + cos ⊖*cos ⊖)/sin⊖cos⊖ = 1/sin⊖cos⊖

[(sin ⊖)^2 + (cos ⊖)^2 ] /sin⊖cos⊖ = 1/sin⊖cos⊖

1/sin⊖cos⊖ =1/sin⊖cos⊖
