Apply FOIL (First, outside, inside, last): (x + 4)(x - 5) = x 2 - 5x + 4x -20 = x 2 - x -20 x(x + 4)(x - 5) = x( x 2 - x -20 ) = x 3 - x 2 - 20x

To see if (0,8) lies on the line y, substitute 0 (the x coordinate) into y = 4x+9 so y=4(0)+9 y=4(0)+9 therefore y= 0+9 = 9since the output (9) is not the same as the respective coordinate (8), (0,8) does no...

The question asks for the roots, this simply means the numbers that could replace x in the equation and the result = 0. There are two ways too do this, firstly either using the Quadratic formula, or my facto...

For example x 2 - 2x - 35 = 0You would have two approaches to this question. You can either use the quadratic formula or you could simplify the expression. Using the formula you would have x = (2+or- (4-4x1x...

Question: 2 1/7 + 1 1/4. Step 1: Rewrite the calculation to simplify (Combine integers) = 2+1+(1/7)+(1/4)=3+(1/7)+(1/4) Step 2: Find the lowest common factor of 4 and 74 8 12 16 20 24. 28 7 14 21 28 Step 3: ...
