Question

use the formula to find
(15002
302X298


answer it fast I want to write paper ​

Answer 1

Answer:

no formula involved

it is multiplication

and the solution of this product is 302×298=89,996

BUT WE CAN EVALUATE IT WITHOUT MULTIPLICATION

THEN

a ^{2} - b ^{2}a2−b2

=

(a + b)(a - b)(a+b)(a−b)

this formula involves

above is the solution with using formula

Answer 2

Step-by-step explanation:

Since x=2 is a root of the equation

2x

2

+kx−6=0

2k+2=0

k=−1

Putting k =-1 in the given equation, we get,

2x

2

−x−6=0

(x−2)(2x+3)=0

x=2,−

2

3

Hence, the other root is −
