7x2 plus 7x5 = 49
7x2 + 68xy - 20y2
What does N equal? Well to solve the problem you would do N+7x1, N+7x2, N+7x 3, N+7x4, N+7x5 to figure out the first five terms.
7x2
x4 + 7x2 - 60 = x4 + 12x2 - 5x2 - 60 = x2(x2 + 12) - 5(x2 +12) = (x2 - 5)(x2 +12)
7x2 -4x -5x2 +2x = 2x2 -2x
7x2 plus 7x5 = 49
14x2-7x2-16 7x2-16 (this can't be simplified any more)
Are you seeking the factors? 7x2 - 10x + 3 = (x - 1)(7x - 3).
7x2 + 68xy - 20y2
(7x2 + 9)(4x - 1)
What does N equal? Well to solve the problem you would do N+7x1, N+7x2, N+7x 3, N+7x4, N+7x5 to figure out the first five terms.
7x2
x4 + 7x2 - 60 = x4 + 12x2 - 5x2 - 60 = x2(x2 + 12) - 5(x2 +12) = (x2 - 5)(x2 +12)
7x2- 63 = -35, when x equals 2
