Answer:

Step-by-step explanation:

Use FOIL method

1) (x +4 )(3x +2) = x*3x + x*2 + 4*3x + 4*2

                        = 3x² + 2x + 12x + 8

                        = 3x² + 14x + 8

4) (4x - 1) (2x + 7) = 4x*2x + 4x*7 + (-1)*2x + (-1) * 7

                           = 8x² + 28x - 2x - 7

                            = 8x² + 26x - 7

Margaret [11]

Answer:

x=0 and y=3

Step-by-step explanation:

If x=0, then we can just plug that value into the other equation and solve for y:

x+4y=12

0+4y=12

4y=12

y=3

Therefore, the solution to the system of equations is x=0 and y=3

we can split the middle term as,

6x^2-15x +4x-10\\

3x(2x-5)+2(2x-5)\\\\(2x-5) (3x+2)

Therefore factors of the given expression are (2x-5) ,(3x+2)
