Expert Solution

Step 1

Given the equations

i) v²-4v-7=0

ii)6p²-p-3=0

We need to :

a) solve the equation either by factorizing or complete the square method or quadratic formulae.

Step 2

$i) v^{2} - 4 v - 7 = 0 w e c h o o s e t h e c o m p l e t i n g t h e s q u a r e m e t h o d b e c a u s e t h e a b o v e e q u a t i o n c a n n o t b e f a c t o r i z e d . v^{2} - 4 v = 7 e q u a t e t h e c o - e f f i c i e n t o f v t o 2 a t o f i n d t h e v a l u e o f a 2 a = - 4 a = - \frac{4}{2} a = - 2 S o {(- 2)}^{2} o n b o t h t h e s i d e o f t h e e q u a t i o n v^{2} - 4 v + {(- 2)}^{2} = 7 + {(- 2)}^{2} L H S i s o f t h e f o r m {(v - 2)}^{2} = v^{2} - 4 v + {(- 2)}^{2} S o {(v - 2)}^{2} = 11 v - 2 = \pm \sqrt{11} v - 2 = \sqrt{11} a n d v - 2 = - \sqrt{11} v = \sqrt{11} + 2 a n d v = - \sqrt{11} + 2 S i n c e x i n t e r c e p t i s t h e p o i n t w h e r e t h e g r a p h c r o s s e s x - a x i s a n d t h e y c o - o r d i n a t e i s z e r o . e q u a t e t h e g i v e n e q u a t i o n t o 0 a n d s o l v e f o r v .
