Question

17.
Simplify 4x² (2 – 3x)+5 and find the value for x = 2​

Answer 1

Answer:

- 59

Step-by-step explanation:

Given,

x = 2

4x² ( 2 – 3x ) + 5

= 4 ( 2 )^2 ( 2 - 3 ( 2 )) + 5

= 4 ( 4 ) ( 2 - 6 ) + 5

= 16 ( - 4 ) + 5

= - 64 + 5

= - 59

Answer 2

x = 2

4 x²(2- 3 x) + 5

By substituting , x = 2

4 × 2² ( 2 - 3 × 2 ) + 5

4 × 4 ( 2 - 6 ) + 5

16 × (-4) + 5

- 64 + 5 = -59

hope it helps !!
