1) x² + 3x - 18
SOLUTION:
(x-3)(x+6)
x times x = x²
x times 6 = 6x
-3 times x = -3x
-3 times 6 = -18
ARRANGEMENT:
x²+6x-3x-18
+6x-3x=3x
FINAL ANSWER: x² + 3x - 18
3) 3(6x-5)(x+1)
SOLUTION:
3 times 6x = 18x
6x minus 5 = x
pero ganto ilagay mo (x-1)
3 times -5 = -15
ARRANGEMENT:
18x(x-1)-15(x+1)
so nagtataka ka na naman kung san nakuha yong (x+1) balikan mo yong question mo beh. don mo makikita.
18x times x = 18x²
18x times 1 = 18x
-15 times x = -15x
-15 times 1 = -15
ARRANGEMENT (AGAIN):
18x²+18x-15x-15
18x² minus -15x = 3x
FINAL ANSWER:
18x²+3x-15
2) 3(x-4)(x+1
SOLUTION:
3 times x = 3x
3 times -4 = -12
same lang to sa 3 beh.
ARRANGEMENT:
3x(x-1)-12(x+1)
3x times x = 3x²
3x times = 3x
-12 times x = -12x
-12 times 1 = -12
ARRANGEMENT:
3x²+3x-12x-12
3x-12x = -9x
FINAL ANSWER:
3x²-9x-12
4) (5x+2)(x+6)
SOLUTION:
5 times x = 5x²
5 times 6 = 30x
2 times x = 2x
2 times 6 = 12
ARRANGEMENT:
5x²+30x+2x+12
30x+2x = 32x
FINAL ANSWER:
5x²+32x+12
5) 3(x+2)(x²-2x+4)
SOLUTION:
3x(x²-2x+4)+6(x²-2x+4)
3x times x = 3x³
3x times -2x = -6x²
3x times 4 = 12x
3x³-6x+12
6 times x² = 6x²
6 times -2x = -12x
6 times 4 = 24
ARRANGEMENT:
3x³-6x²+12x+6x²-12x+24
syempre napansin mo na naman na may same na value na naman so gagawin mo tatanggalin mo sya.
FINAL ANSWER:
3x³+24
