2/3 Using the solve( function With the calculator physical keys between square brackets, and the SHIFTed or ALPHA keys between parentheses, type in the following 8 [^ ] [ALPHA] [ ) ] (X) [ALPHA][CALC]
...solve it with following method. 5x+3y=6 2x-4y=5 So 5x=6-3y so 2[(6-3y)/5]-4y=5 So x=(6-3y)/5 so 12-6y-20y=25 so -26y=25-12 so -26y=13 so y= -(1/2) 2x-4y=5 so 2x=5+4y so 2x=5+4(-1/2) so 2x=(10-4)/2 so ...
...solve the equation x2-13x+36=0 Use the quadratic formula or completing the square. Completing the square: x^2 -13x=-36x^2-2*(13/2) +(13/2)^2=-36+(13/2)^2 The left side can be factored as (x-13/2)^2. ...
...solve(x^3-6*x^2+11*x-6=0,x) or zeros(x^3-6*x^2+11*x-6,x) Note that solve() has "=0" in it while zeros() does not. solve() will give you an answer of x=1 or x=2 or x=3 while zeros will give you an ...
...2. The question says solve for x. On most calculators with a solver function, you can specify a starting value for the variable (in this case x) after pressing [Solve] but before pressing the = key. ...
solve(x^2=21) Too Few arguments Syntax should be solve(x^2=121,x) ENTER or solve(x^2-121=0,x). Solutions are x=-11 or x=11.
for a. a^2 + b^2 Solve the following equation for a. a^2 + b^2 c^2 There is nothing to solve here.You just have an expression with two letters; you have no equation to solve because you need an = sign
