Question

$mx ^{2} - 2x + 3 \: \: \: \:p( - 1) = 7$
​

Answer 1

p(x) = mx2 – 2x + 3 ∴ p(- 1) = m(- 1)2 – 2(- 1) + 3 ∴ 7 = m(1) + 2 + 3 …[∵ p(-1) = 7] ∴ 7 = m + 5 ∴ m = 7 – 5 ∴ m = 2

Answer 2

Answer:

m=2

Step-by-step explanation:

p(x) = m x² -2x +3

p(-1) = m(-1)² - 2(-1) +3 = 7 .....given

=> m + 2 + 3 = 7

=> m +5 = 7

=> m = 2
