X² + X - 42=0

tolong jawab pake cara ya....​

[tex]x {}^{2} + x - 42 = 0 \\ (x + 7)(x - 6) = 0 \\ \\ x + 7 = 0 \\ x1 = - 7 \\ \\ x - 6 = 0 \\ x2 = 6 \\ [/tex]

HP = {-7,6}

a = 1

b = 1

c = -42

[tex]7 - 6 = 1[/tex]

.

[tex] {x}^{2} + x - 42 = 0[/tex]

[tex](x + 7)(x - 6)[/tex]

[tex]x = - 7 \: atau \: x = 6[/tex]
