9xy minus 15yz
why not use real math symbols?
9xy-15yz = 3y(3x-5z)
9xy minus 15yz
= 9xy - 15yz
= 3y(3x - 5z) , not much else can be done
To simplify the expression 9xy - 15yz, we can try to factor out the greatest common factor (GCF) from both terms.
Step 1: Identify the GCF of the coefficients.
In this case, the coefficients are 9 and 15. The GCF of 9 and 15 is 3.
Step 2: Factor out the GCF from each term.
From the first term, 9xy, we can factor out 3xy by dividing each term by 3.
9xy ÷ 3 = 3xy
From the second term, 15yz, we can factor out 3yz by dividing each term by 3.
15yz ÷ 3 = 5yz
Step 3: Write the simplified expression.
After factoring out the GCF from each term, we have:
3xy - 5yz
Therefore, the simplified form of 9xy - 15yz is 3xy - 5yz.
