a3 - 2a2 + 4a - 8 = a2(a - 2) + 4(a - 2) = (a - 2)(a2 + 4)
5a3-45a=-2a2+18 5a(a2-9)=-2(a2-9) 5a=-2 a=-2/5
a2(2a2-21a+49) a2(2a-7)(a-7)
2a2 - 13a + 15 = (2a - 3) (a - 5)
2a2
a2 + a2 = 2a2
sqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*asqrt(a2 + a2) = sqrt(2a2) = sqrt(2)*sqrt(a2) = sqrt(2)*a
(a2 + a + a2) = (2a2 + a) = a (2a + 1)
a3 - 2a2 + 4a - 8 = a2(a - 2) + 4(a - 2) = (a - 2)(a2 + 4)
If I've read your question correctly, you need to subtract: a2 +2a -7 a2 -4a2 +5a2 -6 = 2a2 -6 Note, if x - y = z, then y = x - z; so: 2a2 -6 - (a2 -2a +1) = 2a2 -6 - a2 +2a -1 = a2 +2a -7
5a3-45a=-2a2+18 5a(a2-9)=-2(a2-9) 5a=-2 a=-2/5
a2(2a2-21a+49) a2(2a-7)(a-7)
2a2 - 13a + 15 = (2a - 3) (a - 5)
2a2
What is The simplified form of (3a2 - 5ab plus c2) plus (-2a2 plus 10ab plus 6c2)
No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2
3a4 - 2a2 + 5a - 10 - 2a4 + 4a2 + 5a - 2 = a4 + 2a2 + 10a - 12 = a4 + (2a - 2)(a + 6)
