x=-2 and -32/3
|3x+19|=13
3x+19=13 and 3x+19=-13
x=-2 and x=-32/3
3x²(4x-3)
Step by step explanation:
Factorise 12x³-9x²
first, find the HCF of the terms.
the HCF is 3x²
Then you can use the HCF to multiply all terms, each divided by the HCF.
3x²(12x³/3x²-9x²/3x²)
Dividing, we'll have
let's firstly convert the mixed fraction to improper fraction, and then divide.
( x, y ) = ( -3, 1 )
hope it helps!
8n³ + 4
