Factorise the following.​

good noon please repot this i am bore waba u

viii. 2x(1 - 2x)(1 + 2x)(1 + 4x²)

ix. 4xy

Step-by-step explanation:

viii. 2x - 32x⁵

= 2x(1 - 16x⁴)

= 2x(1² - (4x²)²)

= 2x(1 + 4x²)(1 - 4x²) ( a² - b² = (a + b)(a - b))

= 2x(1 + 4x²)(1² - (2x)²)

= 2x(1 + 4x²)(1 - 2x)(1 + 2x)

ix. (x+y)² - (x - y)²

= (x+ y + x - y)( x + y - x + y)

= 2x x 2y

= 4xy

a negative exponent is translated as follows:

so, we have

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
