Question

2. Write the values of x and for the following quadratic equations.
i) 4x² - 5x - 3 = 0 ii) x² + 9x - 10 = 0​

Answer 1

Step-by-step explanation:

ii)

=x² +10x -x -10

=x(x+10)-1(x+10)

=(x+10) (x-1)

so, either, x= -10 or x= 1

answer

plz mark me the brainliest

plz check the 1st question

still I'm doing that in another method

comparing eq i with ax² +bx + c=0

therefore, a=4

b=5

c=3

now by using quadratic equation

x= -b±√(b²-4ac))/(2a)

putting the values and solving it comes the value

x=

either, 28/8 = 7/2

or, 18/8 = 9/4
