a-^2a-b^-a-b
2a+b=2a+b. Without a value for a and b, the expression has no value.
4a² - b² = (2a + b)(2a - b)
2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
a-^2a-b^-a-b
2a*4b*(-3c) = ? 2 * 4 * -3 * a * b * c = ? -24abc
A=-4 b=5 2a=-8 2b=10 5ab=-100 2a x 2b x 5ab= -8000
A = h/2*(a + b) So 2A/h = a + b and therefore, a = 2A/h - b
2a+b=2a+b. Without a value for a and b, the expression has no value.
4a² - b² = (2a + b)(2a - b)

2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
No. 2a is one thing, 3b is another. If you add them together, they become 2a + 3b. 5ab indicates that multiplication has taken place. 5 times a times b = 5ab

2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------
