A + 2b = c

It's very simple to find the formula for (a+b+c+d)^2. Consider (a+b) be ‘x’ and(c+d) be ‘y’. Then the above problem'll resolve as- (x+y)^2 Now, apply the formula for (a+b)^2- x^2 + y^2 + 2xy. Now put the values of ‘x’ ( a+b) & ‘y’ (c+d) (a+b)^2 +

Simplifying 3a + 2b = c Solving 3a + 2b = c Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-2b' to each side of the equation. 3a + 2b + -2b = -2b + c Combine like terms: 2b + -2b = 0 3a + 0 = -2b + c 3a = -2b + c Divide each side by '3'.

How do you determine the amount of liquid a paper cone can hold with a 1.5-inch diameter and a Consider, a 2 + b 2 + c 2 – ab – bc – ca = 0 Multiply both sides with 2, we get 2( a 2 + b 2 + c 2 – ab – bc – ca) = 0 ⇒ 2a 2 + 2b 2 + 2c 2 – 2ab – 2bc – 2ca = 0 ⇒ (a 2 – 2ab + b 2) + (b 2 – 2bc + c 2) + (c 2 – 2ca + a 2) = 0 ⇒ (a –b) 2 + (b – c) 2 + (c – a) 2 = 0 Since the sum of square is zero then each A^2+b^2+c^2-ab-bc-ac =1/2(2a^2+2b^2+2c^2-2ab-2bc-2ac) =1 /2{(a-b)^2+(b-c)^2+(c-a)^2} if a,b,c are real numbers then,(a-b)^2,(b-c)^2and(c-a)^2 are positive square of every real number is positive. So, a^2+b^2+c^2-ab-bc-ca is always positive Oct 04, 2008 · To counteract, we add a^2 bc - a^2c^2 + b^2 ca - b^2a^2 + c^2 ab - c^2 b^2 to the same side. The complete-square section is a^2(b - c)^2 + b^2(c - a)^2 + c^2(a - b)^2 and the added part is a^2 bc + b^2 ca + c^2 ab - a^2c^2 - b^2c^2 - c^2a^2.
