I would write out the expression as '(x-8)(x-8)' which really shows what the power of...

when a quadratic equation isn't able to be solved using factorisation, the quadratic formula can be used, which has the general formula of ** **. The letters in the formula represent the coefficients in t...

Location is placed where the gradient is 0.Differentiate the line to get dy/dx = -2x + 3 and set it equal to zero.2x = 3 therefore x = 1.5.Plug back into the line equation to find the coordinate. y = -(1....

Answer: (x^3)/3 + x^2 +5 ln (x) .

Multiply out brackets
x² = 4(x² - 6x + 9)x² = 4x² - 24x + 36
Minus x² from both sides 3x² -24x + 36 = 0
Divide equation by ...
