n > 1, n <4.rearrange equations.use the quadratic formula to solve the second equation. look at the boundaries set and formalise which are the answer.
The question is asking us to "solve" the equation which means we need to find the missing variable. In this case, x is our missing variable so our goal is to get all the x's on ...
To solve for x first divide both sides by 9, giving the equation:(x+3)2 = 4/9Then square root both sides, leading to:x+3 = +/- 2/3Finally subtract 3 from both sides leaving:x = -11/3 or x = -7/...
subtract one from the other to eliminate y: 3x+y=11; 2x+y=8 --> x=3substitute value of x back in and solve for y: 3(3)+y=11; 9+y=11; --> y=2
(a) Remember: Multiply each term in the left bracket by every term in the right bracket.(x-3)(x+5) = x2+ 5x - 3x -15.Collecting all of the like terms:= x2+ 2x -15.(b) Solve xJWAnswered by Jack W. • Maths tutor9439 Views
