Simplify: 6y² +7y - 6y - 4 - 3y²
The first step is to group the terms of the equation into y² terms, y terms and terms with no y:
This gives, 6y² -3y<...

(x+3)(x+2)To check this, use the 'FOIL' (first, outside, inside, last) method to ensure the answer is correct.x^2+2x+3x+6x^2+5x+6

Step 1: make one term in both equations the sameHere we will multiply equation B by 2 so that there is a 2y in both equationsEquation C = 2 x equation B = 2y + 4x = 16
Step 2: Combine the equationsIf...
