4.5
No 58 x 5 = 290 but 58 - 5 = 53 so change times to minus
x(-b)=m(x-c)
(x−6)(x+5)
x = 5 + 2x - 3 x = -2
5 x -11 = -55
(8 x 5) - (8 x 1.6) = 27.2
4.5
5 x 6 - 9 - 4 = 17
8 x 5 - 12 = 28
185 x 20 - 5 = 3695
5 x 6 - 8 = 22
No 58 x 5 = 290 but 58 - 5 = 53 so change times to minus
x3-5x2+x is already simplified.
x(-b)=m(x-c)
2x - 3 = x + 5 x = 8
(x - 5)(x + 4)
