Question

For which values of p does the following equation has equal roots?

2x2

-px+8=0​

Answer 1

you can write p as either -4 or -2

Step-by-step explanation:

we can write the equation as the follows:

or, -px=0-8

or, -px= -8

{because we usually keep the variables in the left side whereas we bring all the numbers in the right side for making the equation easy}

now, -px means p*x

so we can write p*x as (-2*4=8) and also we can write (-4*4=8)
