Question

find the value of a and b for the quadratic equation 5x2 - 7= -6x​

Answer 1

Answer:

5x² + 6x - 7 = 0

Comparing the quadratic equation with ax² + bx + c = 0, we get

a = 5

b = 6

c = -7

For finding roots of a quadratic equation we have 2 methods :

1) By factorisation method

2) By quadratic formula method -

x = (-b ± √D)/2a

where D = b² - 4ac

Answer 2

Answer:

find the values of a and b quadratic equation 5x²-7 =-6x
