Question

If p(x) =5x²-3x+7, then p(1) equals

Answer 1

Answer:

$\huge\underline{ \underline{ \red {your \: \: \: answer}}}$

Step-by-step explanation:

$\bf\red{ \mapsto: p(x) = {5x}^{2} - 3x - 7} \\ \\ \bf\blue{ \mapsto:p(1) = 5 \times {1}^{2} - 3 \times 1 - 7 } \\ \\ \bf\purple{ \implies: 5 - 3 - 7} \\ \\ \bf\orange{ \implies: 5 - 10} \\ \\ \bf\green{ \implies: - 5}$

Answer 2

If p(x) = 5x² - 3x + 7 then p(1) = 9

Given :

p(x) = 5x² - 3x + 7

To find :

The value of p(1)

Solution :

Step 1 of 2 :

Write down the given polynomial

The given polynomial is

p(x) = 5x² - 3x + 7

Step 2 of 2 :

Find the value of p(1)

p(x) = 5x² - 3x + 7

Putting x = 1 we get

p(1) = 5 × 1² - ( 3 × 1 ) + 7

⇒ p(1) = 5 - 3 + 7

⇒ p(1) = 2 + 7

⇒ p(1) = 9
