To factor: 10x2 + 27x - 28 Find two values that add up to 27, our middle coefficient, and which multiply to make -280, the product of the other two coefficients. In this case, those two values would be 35 and -8. Now break the middle term down with those two values, and factor: = 10x2 + 35x - 8x - 28 = 5x(2x + 7) - 4(2x + 7) = (5x - 4)(2x + 7)
3x2 + 27x +60
5 + (10 x 2) + 8 ÷ 4 + 1 = 28
4x3+10x2+2x+5= (2x+5)(2x2+1)
10x2 - 20xz + 15xy = 5x (2x - 4z + 3y)

It is: 23-27x when simplified
3x2 + 27x +60
5 + (10 x 2) + 8 ÷ 4 + 1 = 28
10x2 + 101x + 10 = (10x + 1)(x + 10)
4x3+10x2+2x+5= (2x+5)(2x2+1)
The answer is 21
10x2 - 20xz + 15xy = 5x (2x - 4z + 3y)
9 + 9y = 27x -9 -9 9y = 27x - 9 9y/9 = 27x/9 - 9/9 y = 3x -1
Is the same as: 27x+1 = 3 Deduct 1 from both sides: 27x+1-1 = 3-1 27x = 2 Divide both sides by 27: x = 2/27
x=13.5
2275.91 = 28xx = 81.2825
