10x2 + 101x + 10 = (10x + 1)(x + 10)
10 + 10 + 10 + 10 + 10 + 10 + 10 + 108 = 178
x2 + 8x - 20 = (x - 2)(x + 10).
The factors are [3x + 5 - 2*sqrt(10)] and [3x 5 + 2*sqrt(10)].
One method is (10×4)+(5×3) = 55 (or mentally add up from left to right).
10x2 + 101x + 10 = (10x + 1)(x + 10)
(10x + 1)(x + 10)
That factors to (x + 5)(3x + 2)
(x + 10) and (x + 4) are both factors
20x2 - 3x + 10 does not have any real factors.
If that first term is x2, the answer is (x - 10)(x - 10) or (x - 10)2
10
There are no real factors of the expression. The complex roots are: 0.5 +/- i*sqrt(10) where i is the imaginary square root of -1. so the factors are x - 0.5 - i*sqrt(10) and x - 0.5 + i*sqrt(10)
2(x + 5)(5x - 1)
3x + 4y + 10 + 12x + y + 1 First, combine like factors: 3x +12x + 4y + y +10 + 1 Add them (or subtract) as necessary: 15x + 5y + 11
700.
10 + 10 + 10 + 10 + 10 + 10 + 10 + 108 = 178
