It is 4x^2 + 10x - 1

5(x + 4)(x - 2)

1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5

5x2 - 14x + 8 = 5x2 - 10x - 4x + 8 = 5x(x-2) - 4(x-2) = (5x-4)*(x-2)

Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.

If you mean: 5x2 + 10x + 40 Then the only factoring you can do is to divide it by five: 5(x2 + 2x + 8) beyond which it can not be factored. If on the other hand you mean: 5x2 + 10x - 40 Then you can factor it out as follows: 5x2 + 10x - 40 = 5(x2 + 2x - 8) = 5(x2 - 2x + 4x - 8) = 5(x(x - 2) + 4(x - 2)) = 5(x + 4)(x - 2)

I assume you meant x^4 + 5x^2 +10x + 12. The remainder is 28

5x2 + 15 is the same as 10x+15 factor out a 5 since both the 10 and 15 are divisible by 5 now you have... 5(2x+3) and that's your answer

The discriminant is 385.

Same as log(5x2) = log(10).

Yes

5x2 - 16x + 12 = 5x2 - 10x - 6x +12 = 5x(x - 2) - 6(x - 2) = (x - 2)(5x - 6) Whether or not these are in descending order depends on the value of x.

5x2 + 9x + 13 has no real factors.

False

If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.

5x2+500 = 844.45 5x2 = 844.45-500 5x2 = 344.45 x2 = 344.45/5 x2 = 68.89 x = the square root of 68.89 = 8.3 x = 8.3

5x2 + 9x + 4 = (x + 1)(5x + 4).

its 10

Two. x = + i sqrt(8.4) x = - i sqrt(8.4)

5x2 + 3x - 1 does not have rational factors.

5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3

5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1

5x2=10...take 5 two times..5+5=10
