Multiplying the two polynomials using the distributive property .
a) (4x^2 - 4x)(x2 - 4)
b) (x^2+x-2)(4x^2-8)

A) 4x^4 -4x^3- 16x^2 +16x

B)4x^4 + 4x^3 -16x^2 -8x +16

Step-by-step explanation:

A) (4x^2 - 4x)(x^2 - 4)

we apply distributive property:

4x^2 * x^2 - 4x^2 * 4 - 4x * x^2 +4x * 4

so we have:

4x^4 - 16x^2 -4x^3 +16x

4x^4 -4x^3- 16x^2 +16x

B) (x^2+x-2)(4x^2-8)

we apply distributive property:

x^2 * 4x^2 - x^2 * 8 + x * 4x^2 - x * 8 - 2 * 4x^2 + 2*8

we have:

4x^4 -8x^2 +4x^3 -8x -8x^2 +16

4x^4 + 4x^3 -16x^2 -8x +16

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

2 x 503
