Let's factor the given polynomial [tex]\( x^2 + 10x + 15x + 150 \)[/tex] by grouping. We'll proceed step-by-step.
### Step 1: Group the terms
Group the polynomial into two pairs:
[tex]\[ x^2 + 10x + 15x + 150 \][/tex]
which can be written as:
[tex]\[ (x^2 + 10x) + (15x + 150) \][/tex]
### Step 2: Factor out the common factors in each group
Factor out the greatest common factor (GCF) from each group:
[tex]\[ x(x + 10) + 15(x + 10) \][/tex]
### Step 3: Factor out the common binomial factor
Now, notice that [tex]\( x + 10 \)[/tex] is a common factor in both groups:
[tex]\[ (x + 10)(x + 15) \][/tex]
### Conclusion
Thus, the factored form of the polynomial [tex]\( x^2 + 10x + 15x + 150 \)[/tex] is:
[tex]\[ (x + 10)(x + 15) \][/tex]
### Step 1: Group the terms
Group the polynomial into two pairs:
[tex]\[ x^2 + 10x + 15x + 150 \][/tex]
which can be written as:
[tex]\[ (x^2 + 10x) + (15x + 150) \][/tex]
### Step 2: Factor out the common factors in each group
Factor out the greatest common factor (GCF) from each group:
[tex]\[ x(x + 10) + 15(x + 10) \][/tex]
### Step 3: Factor out the common binomial factor
Now, notice that [tex]\( x + 10 \)[/tex] is a common factor in both groups:
[tex]\[ (x + 10)(x + 15) \][/tex]
### Conclusion
Thus, the factored form of the polynomial [tex]\( x^2 + 10x + 15x + 150 \)[/tex] is:
[tex]\[ (x + 10)(x + 15) \][/tex]
