If B=w+9w^2 and A= 3-10w, find the expression that B - A in standard form
To find the expression for B - A, we simply subtract the expression for A from the expression for B:
B - A = (w + 9w^2) - (3 - 10w)
Distribute the negative sign:
B - A = w + 9w^2 - 3 + 10w
Rearrange the terms:
B - A = 9w^2 + w + 10w - 3
Combine like terms:
B - A = 9w^2 + 11w - 3
So the expression for B - A in standard form is 9w^2 + 11w - 3.
