Question

is a is equal to 3 X 2 - 4 x + 1 come be equal to 5 x square + 3 x minus 8 and c equal to 4 x minus 7 x + B then find a plus b minus C ​

Answer 1

Step-by-step explanation:

⇒ 3x

2

+px−8=0

Substitute x=2, since 2 is root of equation

⇒ 3(2)

2

+p(2)−8=0

⇒ 12+2p−8=0

⇒ 4+2p=0

∴ p=−2

⇒ 4x

2

−2px+k=0

⇒ 4x

2

−2(−2)x+k=0 [ Since, p=−2 ]

⇒ 4x

2

+4x+k=0

⇒ Here, a=4,b=4,c=k

⇒ It is given that roots are equal.

∴ b

2

−4ac=0

⇒ (4)

2

−4(4)(k)=0

⇒ 16−16k=0

⇒ 16k=16

∴ k=1
