Question

Find the roots of the equation x2+7x+10=0 ​

Answer 1

Step-by-step explanation:

${x}^{2} +7x+10=0$

$D = {7}^{2} - 4(1)(10) = 49 - 40 = 9$

$\sqrt{D} = \sqrt{9} = 3$

then,

$x = ( - 7 + 3) \div 2 \: \: \: or \: \: \: ( - 7 - 3) \div 2 \\ = - 2 \: \: \: or \: \: \: - 5$

Here you go buddy. Best of Luck

Answer 2

Answer:

x - 5 or x - 2

Step-by-step explanation:

x^2 + 7x + 10 = 0

x^2 + 5x + 2x + 10 = 0

( x + 5 ) ( x + 2) = 0

x - 5 or x - 2
