when x=-1 is​

Answer 1

Answer:

$5 \times + 4 \times 2 + 35 \times + 4 \times 2 + 3$

Step-by-step explanation:

$5 \times + 8 + 35 \times + 8 + 3$

$+ 40 + 35 \times + 11$

$75 \times + 11$

$825$

Answer 2

ii) x = - 1

Sol : Let p(x) =4x2

– 5x + 3

If x = -1, then

p(-1) = 4(-1)2

– 5(-1) + 3

= 4 + 5 + 3

= 12
