Question

Find the roots of the following quadratic equations by factorisation: x²-3x - 10 =0​

Answer 1

Answer:

$x {}^{2} - 3x - 10 = 0$

${x}^{2} - 5x + 2x - 10 = 0$

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

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

$x = 5 \: \: and \: \: x = - 2$

Answer 2

Answer:

X=5 and Y= -2

Step-by-step explanation:

0x

2

−3x−10=0

{x}^{2} - 5x + 2x - 10 = 0x

2

−5x+2x−10=0

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

(x - 5)(x + 2) = 0(x−5)(x+2)=0

x = 5 and x = - 2
