Question

Rewrit using factored form solve using zero product property

Answer 1

Explanation:

a. d^2 - 7d + 6 = 0

(d - 1)(d - 6) = 0

d - 1 = 0, d - 6 = 0 therefore:

d = 1, 6.

b, x^2 + 18x + 81 = 0

(x + 9)(x + 9) = 0

x = -9 multiplicity 2.

c u^2 + 7u - 60 = 0

(u + 12)(u - 5) = 0

u = -12, 5.
