(3x²-2x-4)(2x²+x-3)=3x²(2x²+x-3)-2x(2x²+x-3)-4(2x²+x-3)=
=6x⁴+3x³-9x²-(4x³+2x²-6x)-(8x²+4x-12)=
=6x⁴+3x³-9x²-4x³-2x²+6x-8x²-4x+12=
=6x⁴-x³-x²+2x+12
Answer:
5 crayons
Step-by-step explanation:
A standard pack of crayons is 24, so I put b = 24.
24 + 6 - (x) = 25
30 - (x) = 25
- 30 -30
- (x) = -5
÷ -1 ÷ -1
(x) = 5
I really hope this helps!
Step-by-step explanation:
explanation:
Divide the number to be factored by the prime numbers in turn. Test that result is a natural number. If so, it is a prime factor. Continue until the factorisation is complete.
Answer:
