Question

pls help asap find the value of a b and k please find the answer​

Answer 1

Answer:

From the given equation,

a = 2

b= 5

k = -6

Answer 2

$\huge\bold{Question:-}$

• If 2x³+5x²+(a + b)x- 6 = 2x³+bx²+7x+ k
• Then, find the value of a, b and k

$\huge\bold{Solution:-}$

Here,

Both are equal. It means

• 2x³ = 2x³
• 5x² = bx²
• (a + b)x = 7x
• -6 = k________(1)

So, As 5x² = bx²

b = 5________(2)

-----------------

-----------------

(a + b)x = 7x

From (2) b = 5

So, (a + b)x = 7x

(a + b) = 7

a + 5 = 7

a = 7 - 5

a = 2

From (1) k = -6
