How do I solve (2x-y)(3x+y)

6x^2 -xy - y^2

Step-by-step explanation:

(2x-y)(3x+y)

FOIL

first: 2x*3x = 6x^2

outer: 2x*y = 2xy

inner: -y*3x = -3xy

last: -y^y = -y^2

Add these together

6x^2 +2xy-3xy - y^2

Combine like terms

6x^2 -xy - y^2

Step-by-step explanation:

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
