4a + 7
4a - 5a^2
6-3a**2+7+4a-5a+18 3a**2-1a+31
It is an expression that can be simplified to: 4a+2
so 5a = -20 making a = -4
5a or 4a squared
4a^2 - 5a^2 = -a^2
4a + 7
4a - 5a^2
6-3a**2+7+4a-5a+18 3a**2-1a+31
It is an expression that can be simplified to: 4a+2
so 5a = -20 making a = -4
Because of limitations with the question software, some symbols cannot be rendered, so we don't know what operation there is between the 5a and the 4a-1. Assuming a plus sign produces an inconsistent equation. But if we assume a / (slash) for division, we get a quadratic equation that produces some reasonable roots, so here's what I think the question is: Can you solve the following equation for a: 5a/(4a-1) = 9a-4 ? Yes you can! Multiply both sides of the equation by 4a-1. This gives you: 5a = (9a-4)(4a-1) Expand the right side, which gives you 5a = 36a2 -9a -16a + 4 Subtract 5a from both sides and group similar terms: 0 = 36a2 -30a + 4 Now, use the quadratic formula to solve for a(left to the student): a1 = 2/3; a2 = 1/6
As written, that equals 32a - 8, which factors to 8(4a - 1) If you meant 20a^2 + 12a - 8, that factors to 4(5a - 2)(a + 1)
(5a)^2 or a^2+10a+25
Oh, dude, 5a x 5a is just 25a^2. It's like multiplying 5 by 5 to get 25, and then you just stick that 'a' in there twice because math said so. So yeah, 25a^2, easy peasy lemon squeezy.
