Persamaan KuadratPenjelasan dengan langkah-langkah:
9. 3x²+3x-36
--------------- x 1/3
x²+x-12=0
(x+4)(x-3)=0
(x+4)=0 / (x-3)=0
(x)=-4 / (x)=3
x₁>x₂
x₁=3 dan x₂=-4
4x₁+2x₂ = 4(3)+2(-4)=12-8=4
Opsi C
10. Luas persegi panjang 105 m²
Selisih panjang dan lebarnya = 8 m
P - L = 8
P=8+L
Luas = p x l
105 = p x l
105 =( 8+L)L
105 = 8L + L²
L²+8L-105=0
(L+15)(L-7)=0
(L+15)=0 / (L-7)=0
(L)=-15 / (L)=7
P=8+L / P=8+L
P=8+-15 / P=8+7

~Persamaan Kuadrat______________________
– Soal PertamaSoal
Himpunan penyelesaian dari persamaan kuadrat x² + 3x - 40 = 0 adalah ...
a. {8, 5}
b. {- 8, 5}
c. {8, - 5}
d. {- 8, - 5}
✧ Penyelesaian
x² + 3x - 40 = 0
(x - 5)(x + 8) = 0
...
Faktor pertama
x - 5 = 0
x = 0 + 5
x = 5
...
Faktor kedua
x + 8 = 0
x = 0 - 8
x = - 8
Sehingga didapat:
HP ➞ {x₁, x₂}
HP ➞ {5, - 8} → Opsi B

– Soal KeduaSoal
Jika - 7 dan 4 merupakan akar-akar persamaan kuadrat ax² + bx + c = 0. Maka nilai a, b, dan c berturut-turut adalah ...
a. 3, - 1, dan 28
b. 3, 1, dan - 28
c. - 1, 3, dan 28
d. 1, 3, dan - 28
✧ Penyelesaian
Permisalan:
- 7 → y4 → zMaka:
ax² + bx + c = 0
(x - y)(x - z) = 0
(x - (- 7)(x - 4) = 0
(x + 7)(x - 4) = 0
(x × x) + (7 × x) + (x × - 4) + (7 × (-4)) = 0
x² + 7x + (- 4x) + (- 28) = 0
x² + 7x - 4x - 28 = 0
x² + 3x - 28 = 0
...
Sehingga diperoleh:
HP ➞ {a, b, c}
HP ➞ {1, 3, - 28} → Opsi D

Rumusnya :
A (x,y) = A' (x,-y).
A adalah Titik Awal dan A' adalah Hasil Pencerminan.
A = (7,6).
Maka A' = (7,-6) Jawabannya (A).
