the standard form for writing this is to start from the variable with the highest exponent...\n\n(3a^2+2a+5)-(a^2+a-6)=???\n\n3a^2+2a+5-a^2-a+6=???\n(distribute the negative sign (which is the minus operation for this case) to the second given)\n\n???=2a^2+a+11\n(add those that have the same variable, don't forget to consider the sign)

We could change the second + to 4 by putting a vertical small line\n\n5 + 5 + 5 = 550\n5 + 5 4 5 = 550

6(a^2) – 5a + 1 = (3a – 1)(2a - 1)\n\nI'm guessing that by 6a2 you meant six a squared or 6(a^2)\n\nTo check your answer just do F.O.I.L. (First Outside Inside Last) on the right side to check that it is equal to the left side.

since 2 is a root you take (x-2)*(x-2) and -3 is one also so you multiply (x+3) now you know it is a fifth degree so you need two more so you can take (4x^2+1) and multiply\n(x-2)(x-2)(x+3)(4X^2+1) you do the algebra

i will write u^2 for u to the second power.\nthe question is\nu^2 -3uv-6uw+18vw =\n= (u^2 -3uv) +(-6uw+18vw ) =\n= u(u-3v) + (-6w)(u-3v) =\n= (u-3v)(u-6w)

Plug in 2 for x to determine this:\n\n3(2) + 5 = 6+5 = 11 ≠ 17\n\nTherefore 2 is not a solution.\n\n~ ♥ ~
