Question

Hitunglah nilai p ^2 - 2 qr + 3 p jika

a.p = -2, q = 2,r = -3
b.p = 1,q = 5,r = - 2
c.p = 3,q = 2,r = - 5

tolong jawab dong jawab ya

Answer 1

Kalo nggak salah begini
a. - 2(2)(-3) + 3(-2)
= 4 - 2(-6) + (-6)
= 4 + 12 - 6 = 10

b. - 2 (5)(-2) + 3(1)
= 1 - 2(-10) + 3
= 1 + 20 + 3 = 24

c. - 2(2)(-5) + 3(3)
= 9 - 2(-10) + 9
= 9 +20 + 9 = 38
semoga jawabannya membantu.....

Answer 2

Hitunglah nilai p² - 2 qr + 3 p jika
a.p = -2, q = 2,r = -3
b.p = 1,q = 5,r = - 2
c.p = 3,q = 2,r = - 5
jawab:
a. (-2)² - 2(2)(-3) + 3(-2)
= 4 - 2(-6) + (-6)
= 4 + 12 - 6
= 10

b. (1)² - 2 (5)(-2) + 3(1)
= 1 - 2(-10) + 3
= 1 + 20 + 3
= 24

c. (3)² - 2(2)(-5) + 3(3)
= 9 - 2(-10) + 9
= 9 +20 + 9
= 38
