Please help, will mark brainliest, do not do for points or I will report, explanation please or no brainliest Multiply.
2y - 1
2y + 1
4y^2 + 1

to multiply

(2y-1)(2y+1)

2y(2y+1)-1(2y+1)

4y^2+2y-2y-1

=4y^2-1

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
