Hoofdstuk 4

Vul de gegeven waarden in, in de gegeven algebraïsche uitdrukking en bereken het resultaat.

4.1
Substitueer a = 3

A.
2𝑎 2 = 2𝑥(32 ) = 18

B.
−𝑎 2 + 𝑎 = −(32 ) + 3 = −6

C.
4𝑎 3 − 2𝑎 = 4𝑥(33 ) − 2𝑥3 = 4𝑥27 − 2𝑥3 = 102

D.
−3𝑎 3 − 3𝑎 2 = −3𝑥(33 ) − 3𝑥(32 ) = −3𝑥27 − 3𝑥9 = −108

E.
𝑎(2𝑎 − 3) = 3((2𝑥3) − 3) = 3𝑥(6 − 3) = 9


4.2
Substitueer a = -2

A.
3𝑎 2 = 3𝑥(−22 ) = 12

B.
−𝑎 3 + 𝑎 = −(−23 ) − 2 = 8 − 2 = 6

C.
3(𝑎 2 − 2𝑎) = 3((−22 ) − (2𝑥 − 2)) = 3(4 − −4) = 3 𝑥 8 = 24

D.
−2𝑎 2 + 𝑎 = −2𝑥(−22 ) − 2 = (−2 𝑥 4) − 2 = −10

E.
2𝑎(−𝑎 + 3) = (2 𝑥 − 2)𝑥(− − 2 + 3) = −4 𝑥 5 = −20


4.3
Substitueer a = 4

A.
3𝑎 2 − 2𝑎 = (3𝑥42 ) − (2𝑥4) = 40

B.
−𝑎 3 + 2𝑎 2 = −(43 ) + (2 𝑥 42 ) = −64 + 32 = −32
