Question

which of the following of is a zero of the polynomialp(x) =(x+5) (x-2)?​

Answer 1

Answer:

2

Step-by-step explanation:

$(x + 5)(x - 2) = 0 \\ {x }^{2} - 2x + 5x - 10 = 0 \\ {x}^{2} + 3x - 10 = 0 \\ x ^{2} + 5x - 2x - 10 = 0 \\ x(x + 5) - 2(x + 5) = 0 \\ (x + 5)(x - 2) = 0 \\ x - 2 = 0 \\ x = 2$
