Answer:
a = 5/39
Step-by-step explanation:
We assume you want to solve the equation for "a".
-2 = 4a -7 +35a . . . . simplify
5 = 39a . . . . . . . . . . add 7
5/39 = a . . . . . . . . . divide by the coefficient of a

Answer:
- 8x^3+1 ⇒ (2x+1)(4x^2−2x+1)
- 2x^4+16x ⇒ 2x(x+2)(x^2−2x+4)
- x^3+8 ⇒ (x+2)(x^2−2x+4)
Step-by-step explanation:
The factoring of the sum of cubes is ...
a³ +b³ = (a +b)(a² -ab +b²)
1. a=2x, b=1
= (2x)³ + 1³
__
2. There is an overall factor of 2x. Once that is factored out, a=x, b=2.
= (2x)(x³ +2³)
__
3. a=x, b=2
= x³ +2³
