1) Solving 4a+4b-ac-bc we get (a+b)(4-c)

2) Solving 16a^4-8b we get 8(2a^4-b)

3) Solving x^2-8x+15 we get (x-3)(x-5)

Step-by-step explanation:

We need to solve the following expressions:

1) 4a+4b-ac-bc

We will solve this expression by factoring common terms:

4a+4b-ac-bc

Factoring 4 from 4a+4b and -c from -ac-bc

4(a+b)-c(a+b)

Taking common term

(a+b)(4-c)

2) 16a^4-8b

We will solve this expression by factoring common terms:

16a^4-8b

Taking 8 as common term:

8(2a^4-b)

3) x^2-8x+15

We can solve the expression by breaking the middle term into 2

x^2-3x-5x+15\\Finding\,\,common:\\=x(x-3)-5(x-3)\\=(x-3)(x-5)

Can anybody help me?
lakkis [162]

You know that 6x+3 equals 45 because the two sides are equal. So you first put the equation 6x+3=45. Then you use the subtraction property of equality and subtract 3 from both sides. This gives you 6x=42. Then you divide 6 from both sides to get you final answer, x=7
