x \times x - x \times 6

Calculate

{x}^{2}  - 6x

b.

x(4x - 1)

Multiply each term in the parentheses by X

x \times 4 - x \times 1

Calculate

4 {x}^{2}  - x

c.

2x(5x + 4)

Multiply each term in the parentheses by 2x

2x  \times 5x + 2x \times 4

Calculate

10 {x}^{2}  + 8x

d.

3x(5x - y)

Find all solutions to the equation in the interval [0, 2pi). COS X = sin 2x​
Lera25 [3.4K]

Answer:

Step-by-step explanation:

cos x=sin 2x

sin 2x-cos x=0

2 sin x cos x-cos x=0

cos x(2 sin x-1)=0

either cos x=0

x=\frac{\pi }{2},\frac{3\pi }{2}

or

2 sin x-1=0

sin x=\frac{1}{2} =sin (\frac{\pi }{6}),sin(\pi -\frac{\pi }{6} )\\x=\frac{\pi }{6} ,\frac{5 \pi }{6}
