simultaneous equation
x squared = 4-y
x = y+2

  • Mathematics -

    Express 3x squared + 2x + 1 in the form a(x+p)squared + q where a,p and q are real numbers

  • Mathematics -

    x^2 = 4-y and x = y+2
    sub the 2nd into the first

    (y+2)^2 = 4-y
    y^2 + 4y + 4 = 4-y
    y^2 + 5y = 0
    y(y+5) = 0
    y = 0 or y = -5

    if y = 0 , then x = 4-0 = 4
    if y = -5 , then x = 4-(-5) = 9
