expand 7e(5e-7)+2(9e^2-8)

expand

7 e (5 e - 7) + 2 (9 e^{2} - 8)

53 e^{2} - 49 e - 16

Solution steps

7 e (5 e - 7) + 2 (9 e^{2} - 8)

Expand

7 e (5 e - 7) : 35 e^{2} - 49 e

= 35 e^{2} - 49 e + 2 (9 e^{2} - 8)

Expand

2 (9 e^{2} - 8) : 18 e^{2} - 16

= 35 e^{2} - 49 e + 18 e^{2} - 16

Simplify

35 e^{2} - 49 e + 18 e^{2} - 16 : 53 e^{2} - 49 e - 16

= 53 e^{2} - 49 e - 16
