Question

solve the quadratic equation = p^2+8p=65​

Answer 1

Step-by-step explanation:

Bro it's really simple.

See... p^2 + 8p = 65.

so, we can use the "Sreedhacharya Formula":-

So, p= (-8 +- √(8)^2 - 4(1)(-65))/2(1)

=( -8 +- √324)/2

and now u can solve it further..It's pretty easy..

And yes...Note down this formula and Memorize it cuz it is really helpful Grade 10 onwards..

Sreedhacharya Formula:-

if Quadratic Equation is ax^2 + bx + c= 0,

then, x = [-b +- (√b^2 - 4ac)]/2a

..umm...Write the eqn in ur book..so u can understand claerly...

Answer 2

Answer:

-5,13

Step-by-step explanation:

p^2+8p-65=0

p^2+5p-13p-65=0

p(p+5)-13(p+5)=9

(p+5)(p-13)=0

p+5=0. p=-5

p-13=0. p=13
