Question

a²-55a+ 600 = 0 quadratic equation a²-55a+ 600 = 0 please solve fast​

Answer 1

Answer:

${a}^{2} - 15a - 40a + 600 = 0$

$a(a - 15) - 40(a - 15) = 0$

$(a - 40)(a - 15) = 0$

a=40, a=15

Answer 2

Answer:

Use the standard form, ax^2+bx+c=0 , to find the coefficients of our equation,

a²-55a+ 600 = 0

a = 1

a = 1 b = -55

a = 1 b = -55c = 600

a = 1 b = -55c = 600solution;

a = 1 b = -55c = 600solution; a² = 15

a = 1 b = -55c = 600solution; a² = 15a¹ = 40
