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)

-11a + 7 < -12a + 18 \n a + 7 < 18            .( Added 12a to both sides)\n a < 11                .(Subtracted 7 from both sides)\n\na < 11 (FINAL answer- a is less than 11)

first u distribute the - to the stuff in the parenthesis so you have\n7x^2-3+x^2\nthen combine like terms\n8x^2-3

since no one else will explain it, if u have 7a-5<9. then u have to add five to both sides to get rid of it on the left side. so that makes 7a<14. then to get a by it self, u have to divide both sides by 7. so u get a<2.

it's not factored completely if you leave it as a^2-25 so the proper answer is 5(a-5)(a+5)
