Square roots and squares cancel eachother. therefore the problem is simply:
2.35 + -4.27= -1.92
Answer:x= -1 y= 2
Step-by-step explanation:
I’m not sure I jst solved it in my head
Answer:
times 5/4
Step-by-step explanation:
7 x = 35/4
x = (35/4) / 7
x = (35/4) x (1/7)
x = 35/28
x = 5/4
A) x=-2,1,3(x+2)(x-1)(x-3)=0(x+2)(x2-4x+3)=0x3-4x2+3x+2x2-8x+6=0x3-2x2-5x+6=0 b) x=-3,3,i and also -i(x-3)(x+3)(x-i)(x+i)=0(x2-9)(x2-i2)=0(x2-9)(x2+1)=0x4-9x2+x2-9=0x4-8x2-9=0 c) x=-2,-2,2-3i (also 2+3i), 4+√2 (also 4-√2)(x+2)(x+2)(x-[2-3i])(x-[2+3i])(x-[4+√2])(x-[4-√2])(x2+4x+4)(x2-[2-3i]x-[2+3i]x+4-9i2)(x2-[4+√2]x-[4-√2]x+16-2)(x2+4x+4)(x2-4x+13)(x2-8x+14)you now multiply all three trinomials together
Answer:
Step-by-step explanation:
To solve this problem use the formula "<u><em>Difference of squares</em></u>":
In this problem we have the following equation
This we can write it in the following way
Then if a = x and b = 8 then:
Then the product of both factors is equal to zero when:
Or
