Write the expression 4x^2+32x+70 in the form of a(x+b)^2+c

So firstly, factor 4x^2 + 32x. Make sure that you leave the x variables in the parentheses:

Next, we want to make what's inside the parentheses a perfect square. To find the constant of the perfect square, divide the x coefficient by 2 and square that quotient. In this case:

8 ÷ 2 = 4, 4² = 16

Add 16 to the inside of the parentheses:

Now to cancel out the 16, we have to subtract the product of 16 and 4 to the outside of the parentheses, which is 64. Subtract 64 on the outside:

Now lastly, factor the perfect square and your answer will be

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
