WebWe first check whether p 1(t),p 2(t),p 3(t) are linearly independent are not.Suppose that c 1p 1(t)+c 2p 2(t)+c 3p 3(t) = 0 for some c 1,c 2,c 3 ∈ R. This reads c 1(t3 +2t2 −2t+1)+c 2(t3 +3t2 −3t+4)+c 3(2t3 +t2 −7t−7) = 0 or (c 1 +c 2 +2c 3)t3 +(2c 1 +3c 2 +c 3)t2 +(−2c 1 −3c 2 −7c 3)t+(c 1 +4c 2 −7c 3) = 0. This equals zero for all t ∈ R only if each coefficient … WebThe calculator allows you to expand and collapse an expression online , to achieve this, the calculator combines the functions collapse and expand. For example it is possible to expand and reduce the expression following ( 3 x + 1) ( 2 x + 4), The calculator will returns the expression in two forms : expanded expression 3 ⋅ x ⋅ 2 ⋅ x + 3 ...

Check. 5 x = 125. 5 (25) ≟ 125 Replace x by 25. 125 = 125 It checks. For equations of the form ax=b (a number multiplied by x equals another number), we solve the equation by choosing to divide both sides by a particular number.
