(07.03 MC)

Factor completely 8x2 − 4x − 84.

4(2x − 3)(x + 7)
4(2x + 3)(x − 7)
4(x − 3)(2x + 7)
4(x + 3)(2x − 7)

Good morning ☕️

4(x + 3)(2x − 7)

Step-by-step explanation:

4(x + 3)(2x − 7) = 4(2x² − 7x + 6x − 21)

                        = 4(2x² − x − 21)

                        = 8x² − 4x − 84

:)

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
