Question

ਹੇਠਾਂ ਲਿਖੀ ਸਮੀਕਰਣ ਦਾ ਡਿਸਕ੍ਰਿਮਿਨੈਂਟ ਪਤਾ ਕਰੋ: Find the discriminant of the following equation: निम्नलिखित समीकरण के डिस्क्रिमिनेंट का पता लगाएं : *
x²+5x-6=0
1
48
-38
49​

Answer 1

Answer:

1

Firstly make factors 5x in which by multipling any two numbers we get 6 abd by subtracting we get 5

x^2 + 6x - 1x + 6 = 0

(x^2 +6x) - ( 1x + 6) = 0

take common from both brackets

x ( x + 6 ) -1 ( x + 6 ) = 0

( x -1 ) ( x + 6 ) = 0

if we take x + 6 on other side then x = 1

but if we take x-1 on other side then x = 6

acc. to your option answer is 1

Answer 2

Step-by-step explanation:

discriminant formula =b^2-4ac

here, a=1, b=5 and c=-6

=5^2-4(1×-6)

=25+24

=49
