Answer:
169
Step-by-step explanation:
Square root means what number times its self is a different number. In this case, 13 times 13 = 169 so 13 times itself is 169.
<span>f(x)=4x²-15x-25
</span><span>f(x)=(4x + 5)(x - 5)
</span><span>zero-product property
let </span>f(x)=(4x + 5)(x - 5) = 0
so
(4x + 5)(x - 5) = 0
4x +5 = 0
4x = -5
x = -5/4
x = -1.25
x - 5 =0
x = 5
answer
factor: (4x + 5)(x - 5)
x = 5 and x = -1.25
So, 1=3 2=1 3=4 last one is a maybe but pretty sure
