There are three terms in the given expression
There are 5 terms in the given expression
10a + 15 = 5 (2a + 3)
2a3-16a2+30a Factor out 2a: 2a(a2-8a+15) (2a)(a-5)(a-3) This is the most factored form of this expression.
The terms in the expression 5 x 3y - 634 are 5, 3y, -634
Start with simplifying: 2a + -3 = 5 and reordering: -3 + 2a = 5. Then add '3' to each side of the equation: -3 + 3 + 2a = 5 + 3 and you get 2a = 8 once all like terms are combined. The last step is to divide both sides by 2 and you get the answer, which is a = 4.
If that's -10, the answer is (a + 5)(a - 2). If that's +10, it gets ugly in a hurry.
