10x + 5 which is also equal to 5(2x + 1)
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
(3x2)+5=11
Nice trinomial. Thanks for sharing. It's equal to (x + 5) (x + 2) .
23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
2x² − 7x + 5
10x + 5 which is also equal to 5(2x + 1)
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
(3x2)+5=11
(x + 1) / (2x3 + 3x + 5) --- Can't depict long division here, but you can work this out by seeing if (x + 1) is a factor of (2x3 + 3x + 5). If it is, then the answer will be 1/(the other factor). In this case, that is true. (2x3 + 3x + 5)/(x + 1) = 2x2 - 2x + 5, so the term term above is equal to: 1 / (2x2 - 2x + 5)
Nice trinomial. Thanks for sharing. It's equal to (x + 5) (x + 2) .
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
7x+20-15=7x+5
23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
-8 + 7(6x) + 3 = -7x - 5 - 1-8 + 42x + 3 = -7x - 5 - 142x - 8 + 3 = -7x - 5 + (-1)42x - 5 = - 7x - 642x + 7x - 5 + 5 = - 7x + 7x - 6 + 549x = -149x/49 = -1/49x = -1/49
